I don't see cooling being an issue there will plenty of air flow regardless what direction it moving

Pusher engines do overheat more often than tractor set up engines, unless there is a shroud placed around the propeller AND engine. It is a fact of life, believe it or not.
The heli boys used to (may still) have a special prop nut and a special extension for their starter motors available. Ducted Fan folks too, now that I think of it. Using the correct one of these set ups, you could reach in between the rudders and electrically start your engine. Good luck.
