I would actually argue the opposite, that if conventional victory was possible this invalidates the first two games even more. ME1 and Arrival are both centered around delaying the Reaper arrival until a means to fight them can be found. Without Arrival Liara never has time to check the Mars archives and find the Crucible.
If conventional victory is possible, then it was possible back in ME1, as well.
Not necessarily.
In ME 1, we're sold the idea that the Reapers are powerful, but that their real advantage comes from surprise and control of the Relay Network. They win because they keep the races of the galaxy blind and isolated, preventing them from uniting against the threat. This theme is continued all the way into ME3 during conversations with Javik.
In ME 1 we're also sold the idea that while the Reapers are advanced, technologically, that advantage is not insurmountable. This is further continued in ME 2 with the new Normandy and all the ship upgrades. Now we've not only shut down the surprise blitzkreig advantage, but closed the technology gap to the point that we can compete with a Reaper client race on even or superior ground. We also get little tidbits of additional information on how the Reapers work, and the suggestion that the current Council races have at least enough information about how the Relays work to make building new ones more than just a pipe dream.
So while we weren't ready to beat them in ME 1, nothing in ME1 or 2 leads to the inevitable conclusion that we need to find a superweapon or off-switch to beat them. All ME1 and 2 suggest is that we need to be aware of the threat, united against it, and potentially use the Reaper's technology and strategies against them.
Honestly, all the way through Arrival, and part of the way into ME 3, "Unite the Galaxy into a cohesive fighting force and drive the Reapers back" was still on the table as a viable option. It's not until ME3 that the message really becomes confused and inconsistent.
Up until Priority: Thessia, the only thing we know with absolute certainty about the Crucible is that
it will not work. We know, from the first time Liara describes the Crucible in the meeting with Hackett, that it requires the Catalyst, and that we don't have any idea what or where the Catalyst is. (As an aside, this is where my suspension of disbelief started to fray. There's absolutely no way the Alliance would invest the resources and manpower necessary to build the Crucible if they knew the key component to making it work might not even exist.)
So for the first 2/3rds of ME 3, the story has us uniting the Galaxy to take part in a shooting war against the Reapers. We don't go to Palaven and say "give us your best scientists and engineers, and all the resources you can spare, to build the Crucible". You go and demand military aid in taking back Earth. It's the entire reason for getting the Krogan to help, and ultimately, the entire reason for having the multi-species summit on the Normandy until the Asari bow out. The Crucible is presented as a side project, an unreliable and unknown last resort side project. It's where you send all the stuff and people you find who wouldn't be useful in the main project of fighting a war.
And that's, to me, why 'conventional victory' seems feasable. Shepards actions, particularly in the first half to two thirds of ME 3 only make sense if you're preparing for a shooting war. Because if the Crucible is the key from the beginning, then the Turians and the Krogan are pretty much the last people you need to go talk to. If everyone is really hanging their hopes on this unknown engineering project, then you'd think the first stops would be to recruit the finest scientists and engineers in the Galaxy to build it. You'd be calling up the Salarians and the Quarians/Geth first, and getting them started on the project because the closer you are to figuring out/finishing your superweapon, the easier it would be to convince your military escort to join up.
What's the easier sell?:
"We need you to abandon your planet and send your military to save Earth" or
"We have a superweapon that will destroy the Reapers everywhere with one shot, and we need you to send your military to help deploy it"
Even Hackett is inconsistent in his message. 'We can't win with ships and troops, so get me as many ships and troops as you can. And I guess if you can't get me troops and ships, at least see if you can get me some builders.' I'm not sure he could be more contradictory if he tried.
But I digress.
The reason conventional victory was not possible in ME 1 is because we had just learned about the threat and had had no time to prepare. We had, however, neutralized their primary invasion strategy. By the time ME 2 ends, we've gained further intel about the foe and had a successful battlefield test of new technologies against a Reaper agent race that was, until that point, considered technologically superior. At the start of ME 3, conventional victory is pretty much the only thing we've been shown to work towards, so I don't see how continuing the theme of preparation and unification towards said conventional victory somehow invalidates the games that gave us the theme to begin with.
