Hi Bones,
Actually, it's already been done. Do a Google search for "Tremolino". It's a 23 ft trimaran, designed by Dick Newick, that utilized a custom designed center hull with a pair of Hobie 16 hulls as the amas. I've encountered one while sailing my AI on the South River near Annapolis, MD. It also used the rig from the Hobie as well. They were even available as a kit, where you provided your own H-16 components to complete the package. I don't think they are available any more, but you may find some used ones out there.
Happy Sailing,
