Bath Ventilation Retro Fit w/o Removing Ceiling

I have VERY noisy 20yr old vent/heater/light system (Nutone 665RP) in a 1st floor bathroom that I would like to replace with a similar unit (Broan 100HL) with less noise.

I do not have access to the subfloor and the ceiling is not opened to allow installation to go as they show in the manual.

I'm looking for a method to install the new fan unit strictly from below while the ceiling is place and the only opening is the hole that the unit is mounted into.

Ideas?
