Welcome to AFN, Happy!
Sadly, I've never grown those strains, but I have done autos and photos in the same room, but it can be frustrating to say the least. You do have some options, but I wouldn't put an auto under a 12/12 cycle, their flower time is just too short. In a perfect world (I'm trying to find it, still), I'd have different rooms for autos and photos.
Lets say your autos finish, and you put the photo under 12/12 for flower. Now you have a space that is locked into 12/12, so any more autos you want to crack will have lower yields because of the short light cycle.
2X3 is a smallish room, but doable, just remember to consider floor space before you get things going. Pot size, plant size, fan, max light height, all these things will determine how many plants you can fit.
