Just as food for thought
I have seen pictures of a gentleman in England who's approach to this problem which looked interesting to say the least. The electric starter was mounted to the inside of his flight box on some sort of sled arrangement. The height of the starter was able to be adjusted to suit different aircraft and was sprung loaded with a on switch at the end of its travel. When he went to start his plane he would attach the glow driver and holding the aircraft from behind push the nose cone into the starter which when enough force was applied would engage the electric starter. Never did he have to be anywhere near the nasty end.
It looked easy enough to set up ( harder to explain ).
I have also thought long and hard of a method of eliminating the glow driver ( Apart from an on board one ) and somehow incorporating the contacts in the starter cone thereby eliminating one reason to reach through the prop ( still some late nights to go on that one ).
