Modified Hatfield Split with 4 Workouts: A1/A2, B1/B2?

Hi Coach, just a question regarding your recent article on this subject.
Would it be more beneficial stick to the same WO-A and WO-B routines or would it alright to use two A and two B, each slightly different to rotate thru for a bit of exercise variation?
A1 B1 A2 B2

Thanks in advance for your help
