I've been doing some thinking along those same lines. Here's my dream rifle:
Winchester 94, top eject, take down with 6 barrels. It needs to be in a rifle configuration, curved steel buttplate, nicely figured wood. I want the buttplate, receiver, lower tang, lever and forend cap color case hardened. Straight grip. The configuration of the barrels has me a little conflicted, but right now I think I want them thusly:
1/2 Round 26" barrel in .25-35;
Octagon 26" barrel in .30-30;
Octagon 20" barrel in .30-30;
1/2 Round 16" barrel in .30-30;
Octagon 26" barrel in .32-40;
Octagon 26" barrel in .38-55.
Now, to really set this off from the crowd, I want the lifter (carrier) guide rails, locking lug and hammer polished and engine turned. All the screws and spring cover are to be "fire blue" with the bolt, barrel, magazine, mag cap and link to be done in as rich a blue as possible. Not the "blue-black" that Winchester normally does, but the very rich "Dome Blue" that Colt has on their high end revolvers.
I want the Winchester Pony Express Rider engraved on the left side of the receiver, and my SASS Alias (which happens to be "Griff") engraved across the top of the receiver and inlaid with Gold. And finally on the right side of the receiver have my cattle/horse brand engraved. (Lazy Rocking G). Like this:
