Well, based on what I've seen of him and Sasha in the current arc, I figured he would just take over whatever role Sasha would have had in future story arcs. It's sort of the opposite idea of what happened in season 2 of the anime, where some of his screen time was given to Sasha to keep her relevant.

But, if you scroll down a bit, and look at my reply to Nishinoyaaaa's post suggesting that Franz and Hannah be kept alive too, you'll see that, if Franz and Hannah were kept alive, I would probably have Connie die during the mission to rescue Eren in the Clash of the Titans arc, and then have Hannah take over his and Sasha's roles following the RtS arc.
