I think you read my mind
there could be a nice CNC alloy base machined for this.I have broken the foot off speedlights though, no problem at all!

And give that thought, I would rather the shoe break than have a solid alloy base which would then break the plastic flash case instead if there was an accident. Its better to have a replaceable weak point (though a 1/4" mounting hole would still be nice).

Elv,
I agree abou the benefit of a weak point to protect the flash. Wonder if the foot plastic part is available as a replacement part? Would be easy to cement a 1/4 20 to 3/8 20 adapter in place of the hot foot and then let that break.
