Tom, I've done this with my C6 and a UA T-mount parallelogram mount. It wasn't well balanced (the attachment point wasn't in the perfect position) but it does work, sort of. It was however a bit too bouncy for my liking for anything more than the lowest power wider field work, something that isn't as much of a problem at the lower 25x with the binoculars.
Oh, another crazy idea I have is to try the OTA on the parallelogram I built for the 10 lb binos. I can move them anywhere, and any direction with one finger, and they just hang where ever I let go of them.
I think the fluid head will be a better choice for anything but the very lowest magnifications on the C6.
A slightly angled (or perhaps even straight up) simple wooden alt az style mount(using dob style bearings) would likely work very well with the C6. It's certainly small enough for a table top mount. You'll just have to be a bit careful of the tipping potential. The idea I like is to tip the az axis over in order to approximate your latitude to create equatorial motions. Sort of a mini fork mount like what Celestron offered years ago with the C5 as a table top setup.
