Since it sounds like you are brainstorming, how about a totally different idea.

How 'bout "Teutonizing" it?

7x57R caliber {should feed and function with no alterations to mags, bolt face, etc}, hog's back buttstock, Schnabel fore stock tip, horn buttplate and a little oakleaf carving here and there?

Never seen one and probably never will, but it would IMO be an interesting marriage.

Sort of John Bull meets Marlene Dietrich...
