There is no reason a Tacoma low pinion third member won't fit in the housing, but the steering will get in the way if you have it in the factory 80 location. (behind the axle)
My buddy has a low pinion E-locker in his mini truck front axle, simply because it was available at the time. The mods to the housing are identical between a hi pinion and low pinion 8" locker.

Very cool project! Any plans to plate the front axle housing where the air bumps land? I don't imagine that the stock housing would stand a chance against a few hard hits with an air bump.
