I have no idea if this is practical in RV-12, but instead od a hand hold, would a rope with knots that can be attached inside aircraft, and used as a hand hold to help get in and out by deploying it before enter or exit, but stow inside?
(In hospital beds it is used to allow patients to sit up on bed more easily. Search for "rope in hospital bed to help sit up").

Todays experiments told me that the real problem is getting the canopy open. After that is done, getting in and out is pretty easy! I think it is either a desk type lock on the side, or see if the "hat trick" works for me.
