I have been fueling this debate on other sites, and while I understand lightness is always a top priority when pondered against strength in the MTB industry, I still believe the idea has some merit. The added support for the tire sidewalls when carving turns would just justify the changes, and we would also kiss good bye the snake bites.
Tire beads would certainly need to grow more bubbly in order to be hooked to the interior of the rim, but I don't think extruding the profile in aluminum would be any more difficult than with the existing profiles. We already have multi-chambered aluminum rims, such as Kore's latest creations.
