Schiefspiegler anyone?

Anyone out there have any experience building a Schiefspiegler style telescope with a 16" f4.5 mirror?

I have the mirror and am thinking outside the box on this one (or should I say inside?) .

Everything I've seen on the internet so far is smaller/slower mirrors. Is his even possible?

Any advise is welcome, including telling me I'm nuts and just build another Dob :S .

Maybe not a Schief, but a Classical Cass or Mersenne secondary? (Respectively hyperboloidal and paraboloidal, grind your own.)

If the primary were f7 or so, you could "fold twice" with an X% CO round secondary and same X% CO elliptical tertiary, for low eyepiece height. But that's not what you have.
