Taipan Vet the whole deal

Long story short: After reading all the contributions on zx10wall's power plenum post. i bought one.

I bought a vet in .25 long but really wanted .22.. Now after reading posts from "Knifemaker" on his Raptor and EVERYTHING else on this forum I want to go all out. I"m thinking .22 in the .25 long frame with the power plenum for slugs and if... if... I can get Tony Kidd to do it ( in the proper twist rate) a .920 KIDD barrel (super tension there!) and of course I'll need custom barrel bands/rail to accommodate.If you don't know about KIDD rimfire .22 barrels well.... you ain't seen ....

So what do I need to create the Ultimate? I'm gonna spend the cash, please help me not to waste it!
 
I have a Tony Kidd barrel on a pistol I built and my three rifles cannot out shoot i.t

This built from a 1022 pistol. I bought a laminated rifle stock and cut the shoulder stock off and changed the pistol grip area.
