I'm inclined to think if a game ran poorly on the console then it might run worse on the Vita, even with downgrades. To add to this, the sacrifices that would have to be made to get the game to run at a solid FPS might cause the game to provide a different experience (not in all cases of course). Ninja Gaiden Sigma 2 + is a good example of this. It's almost unplayable at times. I was annoyed by the framerate issues in the console versions, but it is on another level on Vita. I think TN should have made more sacrifices to get it to run smoother, but ... .oh well.
Best they port games that will garner some attention. BL2 is a better choice than say ..... DA:Origins.
Playstation = The Beast from the East
Sony + Nintendo = WIN! PS3 + PSV + PS4 + Wii U + 3DS
