The Reapers would have still eaten you alive if it was.
I thought it was going to be some sort of Dark Matter weapon that used the relays to target the Reapers with a wave of Dark Energy that caused the Reapers to implode on themselves or something. I was sort of right. I was also expecting some sort of finale similar to DA:O, where you have one ending, but different variations of that ending.
I thought it would reverse indoctrination, and make the Reapers lower their barriers and stand still for a whoopin'. I think that's kind of the theory behind the leviathan's ability to take out a reaper, and it was the only (somewhat logical) way I could see to "win."
I suppose the blue flavor did capture some of that in concept, although the Gary Stu Shepard digital reaper god thing made it silly (in my opinion.) Red would have been there if it had been limited to Reapers, but when you universalise it and apply the effect to anything more complex than a toaster oven it too goes headfirst into the deep end of the silly pool.
I think, more than anything, that's my biggest turn-off regarding the ending. Instead of a limited effect that turned one of the Reaper's strengths into a weakness and made them vulnerable, the Crucible empowered and the Catalyst demanded that Shepard Almighty rewrite the galaxy in one of the three color coded images that were presented. It was simply too far, too much, too silly even for a sci-fi/fantasy game.
