Default pcv idea

Well I am sitting at work thinking about my pcv system and what to do with it to make it better....and than I got a random idea that I think might work....

Here is what I got going on in my head...I have an sts system and as of now was going to run the valve covers to a catch can and than a line from the catch can to pre turbo. well I don’t really want to run a line all that way...I already have like 4 going back there. So I am thinking and well I have the air pump off my car right now...well what if i were to reverse the plugs on the air pump to make it suck air and than run the catch can to that? Or just run a switched 12v to the air pump....would that work? How much power does the air pump actually have? I am thinking a lot just because it has to pump air into the exhaust so its fighting against back pressure...so if I just reverse its polarity would it suck enough to work like a scavenger pump?

This could be a really retarted idea but I had to ask.
