Sounds like a good airman making proper preparation, in that case. Though I'd question the need for the extra weight of a second phot......... unless you get one phot helping with the lookout while the other phot is shooting.
High shutter speeds, avoiding any contact between camera/lens/phot's arm and cockpit interior will help. A polarising filter might help with any haze, too.
(And I'd suggest that circuit height - as long as you're nowhere near anyone's circuit - might work better than 2,000 ft and above). 750-800 ft might keep you above mil, and below other PPLs.
Good luck, sorry to have seemed 'forceful' before.
