Kingdom Hearts 1.5 Remix - Is toggleable 60FPS possible?

The 60FPS patch provided via the in-emulator game patches works great for the most part, there are a few things it breaks however:
Cutscenes - character's dialogue goes too fast
Red Trinities - the cutscene itself softlocks at a white screen
Both the PS4 version and the emulated PS2 version with a 60FPS hack have a feature where the game will toggle back to 30FPS during cutscenes which fixes this. Just wondering if this would be possible for rpcs3?

Thanks!
