I don't know. My initial thoughts is not to go overboard with rigging something up for permanent installation.
Biggest reason is, since you free reign why limit yourself to hanging mics. What if the best sound isn't at the ceiling? For example, most venue's I know point the PA somewhat downward, although it sounds like there's low cielings at this place so perhaps this isn't an issue.
I'd think the better scenario would be that, since you have free reign, accept that as an open ticket to be able to figure out each night what is the best taping scenario possible...with no limitations. Having easy access to the venue, the SBD, etc to figure out what will be the best situation for every show.
For example, if you have multiple tapers with only two channels, then put one on the SBD feed, one FOB and one at the stage lip. Then put together a matrix in post.
Here's a real-life example. In the last month, I saw Garaj Mahal and Soulive at a VERY taper friendly venue here in Pittsburgh. I thought PERFECT, I'll do both of these bands MS from the stage lip and it will sound absolutely perfect.
Both shows sound good, but there are things I'd definitely change on both nights. For example, the vocals for Garaj just aren't prominent enough, so I'd either move the mics back a little to get some vocal out of the PA or mix in a SBD feed to get the vocals in there.
OK, so I had it figured out for Soulive right because they had no vocals. PERFECT for stage lip right? WRONG! Turns out that Soulive moved the drums up to the lip of the stage. So for this recording, the drums are just too prominent in the left channel of my mix.
The point is that that every recording situation provides a different challenge if you're gonna get the perfect recording. There are subtle things about every show, starting with placement of the sound sources, that makes every show a different challenge in getting the perfect recording. Keeping the maximum flexibility better ensures you'll be able to get the perfect recording.
So, I'd personally consider the open invitation more an opportunity to have free reign than an opportunity to rig something up permanent on the ceiling.
PS: If you do decide to hang mics, I wouldn't hang them OVER the stage, especially with 10 foot ceilings. You'd never get good balance on those recordings because someone in the band is always gonna be closer to the mics than other band members. Also, speakers are projecting out, not up...not to mention that you'd be BEHIND the PA speakers there. The only scenario I can see where 10 feet above the stage would be OK is a completely acoustic show with a pair of split omni's hanging. Put the mics out in front of the stage.
