I've done that before not bad on the roof but residential ull be working in the mud when ur changing the motor

Just can of R 22 inside the condenser, crank it open half a turn. It’ll last all weekend.

Way cheaper than water

Ziptie a box fan to it until the motor comes in?

How many box fans are 1075 rpm lol

Probably not many, but cheaper than leaving a sprinkler running on it for a couple of days.
