Hi
Sam took the bb out, said it was no problem. its unlikely he could find the 4pin tool but probably used 2x pin spanners.
The mounting holes were already a little damaged so no need here for special levels of care.
You can also make something up, and bolt something over the tool using the axle and bolt, to stop the tool slipping out under torque.
I don't think heat will be of massive assistance, iirc aluminium expands more than ti, although the change in temperature can break a bond.
The thread on one cup is a little damaged, but could be dressed up.
Given how rare a zero bb is, it's interesting they are on this pair of edges. Is it possible that dawes distribution also offered zero?

even without the right tool. I might try and pick up a couple of park tool pin spanners next week. Otherwise it’s off to the bike shop for help. Probably be easier to fit a cartridge bb if and when it comes out.
