Fluid Handling: Push / Flush Different Fluids Possible?

[Blaster]

Okay, so, I was connecting water pipes when I accidentally connected lubricant instead. So I put a tank at the end to collect the lube, and then I pumped into the tank, and ran around a lot trying to get that 0.0 lube out of a few straggling pipes, including tearing up completely and rebuilding several times only to find the magic 0.0 fluid reappears, when I got this idea.

What if you could add a little to the fluid logic, where if a pipe system has different fluids, the fluid with the higher level pushes the lower level fluid down the pipe until it either runs out of room (1 pipe/tank left) or the level matches the other fluid?

It sounds simple to add the logic, and it does two things: greatly reduces the very difficult removal of contamination, and adds the possibility of very cool multifluid pipe systems using circuit networks.

So, what do you think? I could draw pics to explain it better? Already doing this for 0.15? LMK
