You could probably make a script to increase the size, but Adobe programs are pretty bad at hording memory. So, it may crash out if you are working with a lot of large files. I guess you probably have to work in RGB as well because it doesn't seem like they'll make things work in CMYK. No idea on the keywording, since they never really announced a solution for that. Overall, I'd say no. There is no easy way. Maybe, a boycott and hope they switch it back is the easiest solution.
