Idea for Mag p7 thrower... Need input

[bstrickler]

I am wondering if anyone would be okay with adding ~4" to the head of their C or D cell P7 mag, in order to make it a better thrower (with probably almost no flood) (It all depends on if my tests are successful enough to make me happy).

If not many people are willing at first, I'll just make one for myself, then take pics. Keep in mind, this may take up to a year or more to get everything figured out, and in production, if things satisfy my high expectations.
