I'm not saying it wont work, it probably will. But changing every week might not be optimal... but it could... it depends on your neurological profile.
Dopamine dominant could actually use even more frequent variation:
Day 1: Squat layer (Monday)
Day 2: Push A - no squat (Tuesday)
Day 3: SGHP layer (Thursday)
Day 4: Push B (Saturday)
Day 5: Pull A (Monday)
Day 6: OHP layer (Tuesday)
Day 7: Pull B (Thursday)
Day 8: Repeat - back to squat layers (Saturday)
Day 9: Push A (Monday)
Day 10: SGHP (Tuesday)
If you are acetylcholine dominant your set-up is fine BUT I would not train more than 3 days in a row.
If you are mixed type I would stick 2 weeks with the same plan.
If you are GABA dominant you likely need to do 3-4 weeks of each
If you are serotonin dominant you should take up knitting
To know your dominance, look up the "Braverman test"
