Generally, it is the foreground objects (nearby, or otherwise) that make a wide angle totality shot really stunning. For me, I like to remain mobile as well (i.e., move at the last minute if the weather is dodgy) so trying to find a good shot with no near foreground objects, at the last minute, may be too difficult and probably a deal breaker. Still, it's an interesting idea if anyone is willing to try it!
Yes, probably not worth trying unless you have the equipment to spare. It would probably work nicely on your 2008 shots though, since none of the foreground intrudes into the sky. If I go I might give it a shot.
OK, so 1/10s is the limit for bulb via a PC. This is probably OK, as you can choose the correct ISO to not have to go faster than this. This way, you could probably shoot every 1 second, alternating exposures (then combine each set of 2 shots using layer blends). Effective cadence would be 2 seconds during totality, yielding a 2.5 second sequence at 24 fps (for a 2 minute duration totality).
May be a bit less (in terms of fps) if you factor in the 0.2-0.3 seconds it takes to process each shot. Once you run out of buffer this is the limiting factor. What shutter would you choose for the landscape?
The only problem I see with my suggestion of three separate sequences which are cross-faded together, is that there is little room to cross fade, particularly between sequences 2 and 3. I would imagine you'd need at least a second or two of footage overlap to do a good cross fade.
By the way, I have not seen any light curves, but will have a look.
Thanks. I had a quick look but couldn't find anything in terms of EV.
