Pump Mag: X-Valve with Lvl-7 bolt?

[2xFast]

I finally got out and played a little with my pump mag, and after a day of play I started thinking about the possibility of long term wear on the bolt. It would really suck if repeatedly slamming the lvl-x bolt caused the edge to deform..and I know that sear engagement can be temperamental.

I haven't heard anyone mention this as a problem, but all the same if there's a way to make it a non issue I'd like to try.

To that end I was wondering if it's possible to downgrade my x-valve to a lvl7 bolt when I play pump. There are plenty of cheap, spare lvl 7 bolts floating around. If it's possible what parts would I need? Just the bolt and some older power tube spacers?
