So... turns out, I was just about to make a post about this.
I just upgraded my camera from the stock P2V+ (latest/last revision) to a H4-3D Gimbal + GoPro Hero 4 Black.
I actually have a P3P as well, but I got a steal on the GoPro and I wanted a way to bring some life back to my old bird.
At least on Android, it works flawlessly, both with the stock app and with Litchi.
Usual considerations of course.... no control over shutter, ev, etc while in flight, though I'm looking at a way to hack the GoPro's wifi into the existing P2V+ wifi-stream. We'll see how that goes at a future date.
FPV does work though as does control over the H4-3D gimbal.
In fact, you get full 0-90 degree tilt and when enabled, +30 to -30 tilt. Aka, you can look up, and look slightly backwards as well.

All the instructions you need are here:
RC Groups - View Single Post - DJI Phantom 2 Vision+ Plus 2.4ghz Wifi Module - wiring diagram / camera connection
No soldering and no additional parts required (though you might wish to purchase a longer 8-pin cable).

Few notes:
- You might need to get creative with cable routing. I got lazy and removed a single fin from the ventilation hole to route my cable.
- Be careful when moving the single pin on the 8 pin cable. Use a small tool to release it, don't just use force.
- Took me about 3-4 hours from beginning to end.
- After install, you'll need to connect to vision assistant and adjust the gimbal pitch options to fully enable control over the H4-3D.
- It's been reported the H4-3D only works with Android. I don't use iOS products for flying, so can't say myself one way or the other.

Few more notes:
1) If you're starting fresh, the best option is just to buy a P3A or P3P. Hand's down.
However, if like me, you already have a P3P, swapping for the GoPro is a nice way to extend the P2V+'s service life.
2) While analog video is often more reliable than the WiFi setup in the P2V+, with the Itelite panel, a 3rd party access point (swapped for the stock range extender), and FPVLR's linear polarized bird-side antennas, I get nearly the same FPV range on my P2V+ as my P3P (and that's with FPVLR's antennas and boosters).
The controller-side is admittedly a bit clunky (I carry a power pack in my pocket), but it works well for me.
I also boost the 5 GHz control signal and my replacement access point is slightly higher power than the stock range extender. I've also software modified the P2V+'s wifi module for more power output, tweaked the DHCP server, and changed from "WDS" to regular "Access Point" mode.
3) Finally, I have a "late revision" P2V+, with upgraded ESCs/motors, vented wifi module, and the sticky goop on the motor wires. In addition, I've found the internal wiring has additional interference chokes, glue to hold connectors in, and braided cables in some places where the older P2V+s didn't.
All in all, for a "last generation" UAS, she's still pretty capable.
