Restore/ hot rod an air compressor?

[68 SWB]

So I've got parts from two different air compressors that I thought about building a good one out of. The pump I have was from a working compressor that the motor went out on. The "complete" compressor I have the pump is bad on and maybe the motor also, but the tank is good. The rpms for the motor on the complete compressor are too high for the good pump anyhow.
So what do you guys think... new motor, rebuild pump, cleanup and custom paint the tank? We build custom trucks, why not a compressor?

Edit: not sure why attaching the pictures rotated them.
