Well, given that the frame will almost assuredly be an investment casting, that neat contour should not be cost-prohibitive. Ruger's manufacturing gang should be able to make it nice, if the bean-counters say it's worth the effort.
One thought . . . if there's not much difference in the price between the "improved" Bearcat and the existing Single-Six I'm not sure this would be a viable product. Ruger wouldn't want to have two of its offerings competing with each other for market share.
On the other hand, with the addition of the Single-Nine, the Single-Ten, and now the Single-Seven in 327, perhaps Ruger feels the need to boost single action interest . . . hmmm?
