ERMAGHERD how much do those weigh (8.3 kg :o )
being able to shift the caliper in is good though, there's 77.5mm of friction surface there I think, 150mm bell, they'll fit under a 15" MO at 310mm, TD pro race 1.2 not quite but that 2.5mm might just do it.
here's a nicely details drawing of the 406 305mm disc.
and here's those behemoths you've picked up
