How do you hold both the Vita while using an additional controller to play the game? Wouldn't you have to place the Vita down flat or prop it up like a tiny monitor while holding the controller? When you use remote play where do you play it?

I can see how your hands would start cramping up with all the back-touch pad tapping. I have a Vita, but no PS4 so I can't say I've attempted playing it via Remote Play. Can't say I would really want too either. It makes a lousy PS3/4 controller, and I'd rather use an actual game-pad than the Vita. But I see using a game-pad with my Vita is like using a compact keyboard with my iPhone.

This is just my opinion though. If you seriously think you'd use a game-pad with the Vita than I'm all for it.
