>>>You might find Parker Ackley's tests interesting. I can't remember if it was a Winchester or a Marlin lever action, but he cut off the bolt restraints and fired a round with no damage to the rifle, and the bolt didn't even open. I think it was a 30-30, but not certain.<<<<

I have read Ackley's test. I am sure you can find a way to make that happen.
However they put locking lugs on bolt for a reason. Other wise the hammer could just hit the back of the cartridge with no rolling block required.
