I will test openplotter fresh on a pi 4 and a pi 5. Ensure there are no problems and work on a video detailing everything.
Your hydraulic system seems well suited for my midpower motor controller. You could study the schematic:
pypilot.org/schematics
To use IBT2, you are somewhat on your own unfortunately because I do not use the IBT2... The main reason is because it has terrible terminals (you could remove them and solder wire directly to board though) in fact you should probably solder all connections including the control pins. The path resistance of 16m is already more than 3 watts (in reality it is probably worse) which is quite a bit of loss but potentially bearable. Where my controller is 1m for mid power (1/4W) or 0.5m high power (1/8W) at 15 amps. Otherwise it should be possible to use but I would have rated such a part for 5 amps. The 43 amp rating is "optimistic" given it would dissipate 30 watts or more it probably would need a fan to achieve this (much less reliability), and also consider life of things like capacitors decreases significantly with higher temperatures...
I do like the low cost, but if I were to take an IBT2, and add the protection and features of my motor controllers, it would cost me basically the same to produce as the controllers I already make with more heat generated. Some day if I could ever make runs of 1000 parts, you could see all my prices cut in half!
