Source for a 12 string piezo tune-o-matic

I'm building an ES-1Q and I'm thinking that I'd really like to have the option of getting an "acoustic-y" tone with a piezo bridge.

I've found plenty of 6 string piezo bridges, but no luck on 12 string bridges.

Does anyone know of a source for something like this, or has anyone had any experience in converting one?

Thanks!

Converted a 6 string piezo bridge to a 12 string. A bit ugly, but let's hope it works!

No reason why it shouldn't. The downward pressure on both side of the saddles should be fairly even.
