Nice! I would swap with a guy in Iowa, the trigger bar. You don't need no stinking CDST, when simple single trigger is so much simpler!
Seriously, I would not chase the barrel much unless you really like the caliber and that particular chamber and throat. I'd bend the tang (with super care) and make it a pistol grip. I'd put whatever caliber I happened to "need" into the barrel. Then I would restock with some high-contrast English walnut and case color the action.
Then I would kill something with it. Or shoot a match or three.
But that's just me.
