Dang, you've just re-invented the Benet - pronounced 'benay', not berdan or boxer - inside primed case.
Good news, bad news.
Good news, patents on the Benet priming system have surely run out. So maybe you can grab it up.
Bad news, those patents were not renewed over 140 years ago for a reason. Enter Messrs. Berdan and Boxer.
As I mentioned before, you still have not addressed the unsupported extraction groove in your drawings.
Cartridges develop pressure - the .22LR is rated at 24,000 psi - in order to push the bullet into and through the rifling with enough force to give velocity to the bullet.
This pressure would blow out the thin sidewalls in that extraction groove every time, and probably shear that rim completely off.
My take, JT
