Changing EI on the same film would be difficult if not impossible to develop proprerly I think. Personally I would just go with the fastest EI I think I might need. Also, I wouldn't take any chances on slow film. My personal choice would be Delta 3200 exposed at say 1600 for the whole evening.
Good luck!
