Oh! I don't think it would work at all that way round with standard Monster footrest hangers, as the shoulder bolts would disappear in the counterbores and you'd have to turn it over anyway. Besides being too thick for the bolts to reach.
It looks as heavy, if not heavier than a standard steel one and renders the brake virtually rigid with that geometry.
Bitza made one from a bit of 1/4" Dural I sent him, along with a pattern.

The rose joint will go either side, so that's not important.
