What other major issues am I missing here and could this be worth the obvious risks?

A huge issue will be the computer and sensor connectors.

These connectors use tin plated pins. Overtime they will oxidize and cause all kinds of issues - loss of gps, engine CHT and EGT, rpm, manifold pressure, fuel flow. Additionally the spark plug wire springs will corrode. The roll trim motor and pitch trim motor will need to be replaced - the commutator will have oxidized.

I can understand motors and bearing surfaces corroding, but why would connectors corrode more than an airplane being flown? Just curious. Does vibration with use protect them?
