I think tilt would be a benefit. There is NO perspective distortion using tilt--keep the BACK level and straight and you can do whatever you want to the front, as long as the SAME thing is done to both lenses. Try it out first using a view camera with a shift bar. The tilt on both (just hinge the front with both lenses at the bottom to allow this---same hinge--the lensboard should hold both lenses) will allow you to get more foreground in focus--you can use less stopping down to get some subjects in focus. Try it and you will see. Tilt changes only the plane of focus and has nothing to do with perspective.
OH--as for usefulness...only for when you want far away and VERY close in exact focus--this is only really needed with larger formats--the smaller formats--shorter lenses--they will have enough depth of field.
to tell the truth--building a camera is a real undertaking--lots of things to get working--I'd make it as simple as possible first (no tilt) and then ADD the tilt facilty later---should be an easy add.
I'd advise to build it first...THEN add the doo dads later AS NEEDED--the simpler the lighter and more rigid.
