Advise for AC condenser outdoor unit on high-rise

[Peak]

I'm on the 9th floor of the exterior masonry building 17 floor. No balcony, only fire escape.
I want to install multi-zone mini split system. I will probably use Fujitsu because they have the smallest condenser outdoor unit.

The only resource I can find on the internet is from a company in NY where they installed the condenser on window ledge.

Should I give up on this project and stick to window a/c ?

Will the building owner/ coop even let you do it? Looks like a service nightmare.

Dealing with a company that has done this work before and is used to working in a hi rise is a plus. Do you pay your own electric.? The reason i ask minis are energy efficient, quiet but i can see service expensive. In downtown st. louis company i work for has done alot of buildings that were factories or office buildings that have been converted to lofts have water source heat pumps. Heat pumps in each apartment and can have either heat or air anytime.
