Can I create BAIJ matrices with different size blocks for different block rows?

Sorry, this is not possible, the BAIJ format only supports a single fixed block size on the entire matrix. But the AIJ format automatically searches for matching rows and thus still takes advantage of the natural blocks in your matrix to obtain good performance. Unfortunately you cannot use the MatSetValuesBlocked().
