Thats basically what OS did with their EFi system, and they used the remote needle valve to set the bias pressure.

Thats the issue with crankcase blowby, especially with 4 strokes decreasing with rpm... and with OS's EFi system, you had to adjust the tank pressure to optimize the performance... and that was never a constant either... the raise and fall of tank pressure that follows rpm / exhaust pressure has always worked well, and trying to artificially recreate that can be done, but to what level of accuracy, and reliability... the more ancillary equipment you add, the more it affects the serve life, and reliability... but Isolating the contaminates in the exhaust pressure feedback to the tank, would be an improvement though, get rid of the crap trap.
