You should be fine leaving the fuses as they are and getting roboRIO power from the PCM-labeled connection. It won't be legal for competition use, but everything should work. You could also power the roboRIO from a regular PDP output instead of the "dedicated" one.

I think you might be confused about what the purpose of the fuse is. It doesn't change anything about how much current is supplied. All it will do is open up the circuit completely if something pulls too much current, to protect the wires from overheating.
