One more question

And this is just purely hypothetical (for me, anyways...)

If you built a Schmidt-Cassegrain with a 10in F5 primary, placed the secondary at the appropriate place, but used, say, a 4in F6 (whatever proper ratio that would put the focus in the appropriate location at the back end) instead of a flat mirror, what:

1) would the total focal length of the entire scope be?

and

2) would the magnification with a given eyepiece be?

Thanks, just a danken experiment for me, and i can't logically justify any of the solutions I have thought of...
