Sets/Reps?: 5×5, 8×3 & 6×4?

Im currently doing a full body workout. Focusing on Squats (Mon), KB Clean & Press (Wed), and Deadlifts (Fri). (I also do other exercises those days but my focus is on these Big 3) Ive been sticking with 8×3 (1.5 min rest) for a few months now with good results but I feel its getting stale. I dont want to change these exercises for these are my bread & butter or foundational movements.

My question is should I rotate my sets and reps for these exercises say every month to spice things up and handle different loads? My load would be heavier for 8×3 than 5×5. Or should I stick do a fixed set/rep range?

Im thinking something like this for example:

Month 1
————
Mon – Squats 5×5 (2 min rest)
Wed – KB Clean & Press 6×4 (1.5 min rest)
Fri – Deadlifts 8×3 (1 min rest)

Month 2
————
Mon – Squats 6×4 (1.5 min rest)
Wed – KB Clean & Press 8×3 (1 min rest)
Fri – Deadlifts 5×5 (2 min rest)

Month 3
————
Mon – Squats 8×3 (1 min rest)
Wed – KB Clean & Press 5×5 (2 min rest)
Fri – Deadlifts 6×4 (1.5 min rest)

Would like to hear some feedback on this & thanks.
