Personally, I would not do it. I see no reason to own the Glock 30 and the Glock 36 together. The glock 36 is basically a slimmer glock 30.
Either one is good enough on its own. Sell the kimber if you don't want it and buy the G36 or the G30 (whichever you like better). Then use the other half for ammo or a different gun.
