Increasing Air Flow In An Sm 500?

So, my question to SM 500 modders is this: can the opening in the back of the barrel where the trigger valve plate rests be widened safely? Even when using a flashflight, I can't see the edge of the rubber ring that rests against the opening. if it is wide, the opening could be widened quite a bit. But, if the rubber ring is not wide enough, I will wreck the gun if I widen the opening. There is no way to access this part by opening the gun - it is only accessible from the barrel after sawing the muzzle off.
A picture won't help because if you could see what I need to see, then this question would be moot. If you've modded an SM 500 before, you will have seen the firing plate/rubber ring and the size of the opening. I rarely ask modding questions, but I don't want to do something undocumented to a rare gun without some advice.

I don't know the pump shaft diameter either, but I'm sure it wouldn't harm replacing the pump and then leaving the quick release valve functional. If anything, I'd try to lengthen the life of the blaster, since SM500's are way cool as it is.

There definitely is a feel that it lacks power. I tried an in-line clip on it since 3/4" CPVC fits in the white barrel - it worked pretty well except that each shot went about 45ft. Also tried an RSCB with similar range reduction.

7" of the usual Home Depot CPVC, although it is a "thinwall" version from Eastern CT that makes a perfect fit with white foam. In a springer, the fit is actually too loose for any other type of micro except the '06-'07 Frost King foam, which is why I shoot white. But, I guess since it's an air gun, it really likes those loose-fitting slugs. I found out today that it also likes BB and fishing weight darts, just not the slingshot ones.

The gun is not a powerful gun by any means, the main attraction is the comfyness and looks of the shell.
