If it is a kit for the masses, then it probably should be some kind of wood for the masses, Hickory, Ash, or some other common hardwood.
I've often thought that a DIY kit that uses an RB or RZ 6x7 back. Maybe a mono rail with only a little bit of movement in the front and rear standards. Just something that wouldn't be too expensive to get into a view type camera that would take "common" film backs and lenses. Basically a starter view camera that might allow someone to get their feet wet and decide if they wanted to go bigger or get out.
