What to do with these two lovelies?

I still can’t decide on what configurations to build with these two lovelies.   I think one should be a pistol at least.  They were both transfered as “pistols”, so maybe both into pistols.  Light weight builds, but they don’t have to be airweights.  Maybe one pistol and one light carbine?  I want them to be unique.
Post links to images of suggested builds and the Parts I should buy for the builds.  Help me out here.
