rear end question, 10 bonus points available

here is a new question for thought. suppose you own a tffc strange 12 inch diff or a christman 10.5 diff. does the new 11 inch mark williams ring gear have the ability to be installed in these housings allowing a lighter than the mw housing assy? and adding a possibly stronger ring and pinion to a chrisman diff. anybody know about this one? i know the 11 inch is proprietary to mw, but they do sell the gears only.
