Yep. You can do your optomcas app in late summer/early fall and do your oat in the winter.
The only thing I might be careful about is your timing of biochem... From what I understand you should really take Orgo 1 before biochem and it's usually a prerequisite. Also, I've heard A&P can kind of help with OAT, so, if you can, I'd switch biochem and A&P places.
