Dr. Diff BBP axles with 11 x 2.5 Drums

Swapped out my Moser 35 spline axels/spools yesterday with a suregrip and the Dr Diff axles and discovered that my new BBP A-body 8 3/4 axles from Dr. Diff will not work with my existing 10" x 1.75" redrilled drum setup. I'd like to go disk on the rear but all the kits are so expensive. The 11 x 2.5 drum setups seem to be readily available, though on the heavy side.

Will the 11 x 2.5" drum setup fit-up to the Dr. Diff axels ok? I was a little disappointed to learn that the DrDiff axels are also ~ 1/4" wider on each side. I see plenty of discussions about it on FABO but it wasn't mentioned on his product description when I made the purchase. My wheel/tire combo is already pretty tight in my Early A body.
