C&Ku combos imo are always a compromise.

If you have a prime focus dish you might be able to use a bullseye feedhorn.

Nothing for a CM dish I guess that will do both ?

Titanium satellite has a Combo (CK1S), to which you can fit a conical scalar. This may work to some degree, but remember the scalar is different for C and Ku band, so it will be a compromise design.
This may work for normal TV watching, but if you are motorising and/or feed-hunting anyway, I would think you're better off with an off-set C-band mouned slightly left or right of the center Ku.

With an offset dish like the CM design, you might get better results fitting the second (C band ) LNB, above the Ku though you will have to fit a second motor to move the reflector to the correct point.

If you have the money and space, put up a second dish.

Erhm... I didn't write the last two paragraphs (highlighted).
While the claims may be perfectly valid, I cannot vouch for them, as I have no experience in using these techniques, and therefore cannot give guidance in that subject matter.
