Is there a roll film back for 4x5 that can do both 6x7 and 6x9, with the flip of some handy little switch? Or is this just wishful thinking?

Sinar builds the Vario-Zoom backs that can do 645, 6x7, 6x9 and 6x12. It's not quite as simple as a handy little switch, and not quite as cheap... but these holder are known for their film flatness.

The Sinar Zoom II can do any format from 645 to 6X12 - and on the same roll! It's a very nice piece of gear, but quite expensive. FWIW, Robert White currently has them on special - see their website (www.robertwhite.co.uk).
Sinar Zoom II- 'Slip In' International fit RFH - adjustable from 6x4.5 to 6x12 - probably the Ultimate RFH - supplied with 'zoom' screen mask... but quite expensive even at robertwhite :

Ooops. I appreciate the replies, but I am breathless. Let me add another criterion. It has to cost less than what I normally pay for cars. Wow, that Sinar stuff is exxxxxxxxpensive!
Since I don't care about the other formats, and I don't need to change in the middle of a roll, two ordinary backs would be much cheaper. A combination back is probably just wishful thinking. Oh well.
Not 6x7 but the Shen Hao 6x12 back comes with 6x4.5,6x6,6x9 and of course 6x12 masks. Not very expensive. At least not direct from the factory.
There's a Dayi 6x12 back that does a few smaller formats (maybe 6x6, 6x7, and 6x9, possibly 645). Here it is at Badger--

You can also find them from a Hong Kong dealer on eBay who goes by "oneworld3." Not as fancy as the Sinar, and I don't know that you can switch midroll on the 612 back, and it relies on the red window instead of a frame counter, but I have their 617 back and it seems to work well. On attraction of such a simple design is that there's not much to go wrong.
Don:
Where do you buy cars for $1900?
Looks like Nick and I were posting at the same time. It would stand to reason that a back that uses the red window doesn't do 6x7, since the numbers on the paper backing correspond to 645, 6x6, and 6x9.
Glenn,
I didn't say I was PROUD of the cars I normally drive. But I CAN stand on the roof of such cars for extra tripod height without any concern for marring the finish, so to speak.
