Suspension ear reinforcement, Would this work? (pic) Options

[smrz914]

I played around with photoshop a little bit. I hope 914RS doesn't mink I used his picture.

Anyway, instead of having a tube go from the ear to the firewall, I thought that one could take some sheetmetal and create a shelf. I don't thin this will work for /4 but it might for converted cars. I thought a cross section might look like

Would this be strong enough? Just seeing if there is a nice way of doing the brace. So It would be like having another shelf. I don't know how low the engine mount goes but I think one could work around that. On the ear the attachment point would be pretty low and be able to handle movement better. On the firewall site it would attach to the back edge of the floorpan.
