Can Alembic make electronics including bridge Peizo pickups? I'm thinking something simple like vol, pan, filter, q switch, and magnetic/piezo pan.

Glancing at a few prior threads, I believe it is the case that Alembic has tried incorporating Peizo pickups into their electronics before and were not happy with the results.  So I think the answer would be that they would not want to do that.

If you are interested in combining Alembic electronics with piezos, check out this thread about a guitar in which I did just that:
