As for the pulley count and placement, I seem to remember a best practice of having a pulley between each cogged wheel in a machinist environment ... not sure if that applies to engine bays ... It's been years since I had that training ...

I don't know how a cogged belt would react to the cyclical compression of the cogs caused by being under tension while running over a smooth faced pulley. My thought is that the belt wouldn't like it at all, which would either diminish the belts life, or require cogged idler pulleys.
Two pulleys would still satisfy that best practice, would it not? My thought is that there would be two pulleys on either side of the compressor, but lower instead of above the compressor pulley.
I'm not trying to argue here, I'm just trying to expand on my earlier post to ensure I wasn't misunderstood. I posted my idea expecting to be told it wouldn't work, I'm just not sure why it wouldn't work.
