What motivation would an apostate have to become a Grey Warden?
Avoiding death at the hands of a group of templars.
Hard to say how Duncan would find one before the Templars, which could either use a Phylactery to track the apostate down or meet one by chance. And why would Duncan want to recruit an apostate mage, if he can get one so much easier from the Circle? Perhaps if Duncan met one by chance, which is so unlikely, that it'd IMHO be difficult to make a credible story out of it. At the same time the apostate needed to feel cornered e.g. by Templars, so he/she'd be willing to join Duncan instead of being killed.
I doubt, Duncan would have gone to Flemeth to ask Morrigan to be recruited for example. And I doubt even more, that he'd be successful. More likely he might have gotten himself killed.
Anyway, even with the joining it might be IMHO unlikely for such a character to pursue the goal to fight instead of running away, which at least is a theoretical option even mentioned by Morrigan. Ok, the apostate may still feel indebted by Duncan saving his hide, but I wonder if gratitude would last that much.
Ok, one possibility would be, if there was a mage background linked to the Dalish, because obviously there are some with magical abilities, Duncan is at good terms with the elves and visits them, ... Then again the Dalish would probably claim such a mage would be indispensible for them. Already in the Dalish origin I felt pretty much the least motivated to help saving the (mostly human ruled) Ferelden. The Dalish only goes with Duncan, to save hsi/her own life. (Might work actually with a Dalish Mage, too.) So, my conclusion is: I don't know. But unless there was a different Dalish origin for mages, that mage would have no clue about the Fade and demons...
