The RUmba 32 will be an easier change if you’re up for it, it should drop right in, but requires different firmware. The BTT SKR Pro is a better board though. I do all sorts of experiments on my board and having 144 pins, gives me the freedom to make those changes.
Ive never used either on the Beast V2. Never found a need except for the additional memory to use for distortion mapping, which IMO isnt needed anyway.
