Could a rebranded vita be successful?

With far better support and marketing, updated, but not too expensive, HW and display and 100% BC it could extend PSV life and sales up to decent numbers, MAYBE.
Mobiles stole the casual gaming, but anything more than casual sucks on them from mildly to horribly, so there's still a market for portables, but it's a lot smaller than in glorious DS and PSP times.
So 100% BC would be of the essence for PSV2, as without it it would do even worse than PSV.
I wouldn't excpect anything more than decent overall PSV+PSV2 sales anyway, as the last decently big chance for portables was for 3DS and PSV, and while Ninty fixed its initial mistakes quick enough, Sony wasted its chance.
Switch will obviously get the lion's share of an eeven smaller market next portable gen, adding a chunk of home users too, so Sony will have little space for PSV2, as it already has a winner, PS4, for home consoles market and it won't damage it with internal competition, so at best PSV2 would just benefit with better integration with PS4 and better "portable games on TV" functions, but it won't be a true hybrid like Switch.
That big MAYBE though could be enough for Sony to give up, but I wouldn't exclude a less ambitious PSV 1.5 (better HW specs, with upscaled graphics and totally optional better settings for new games, like a PS4 Pro, but not a new platform by any means) and some marketing and support effort better than now, but with costs strictly kept under control.
