Speed endurance and weights

Yup, I used to dedicate two full weight room days and additionally one upper body training in context of a tempo-like session. But they were quite heavy sessions consisting of two main lifts and several auxiliary lifts. Example of lower body training what I used to do could be something like:

back squat 3x6
single leg press 8-6-4-2-8
hamstring curl 3x8
RDL 2x8
barbell hip thrust 2x10
and some contrast plyos in between

Then when the in-season got closer I switched to power clean, jerk, plyos and dropped general lifts.

So all in all, this CF-like training is a big change for me. I’m quite strong already (bench press 310, power clean 300, back squat 420) but I’d be happy to get stronger of course.

Would it be a disaster if I kept lifting in the rep range 5-8 in the early SPP and later in the SPP start lifting 2-5? Also, the lifts that RB34 listed in the program - is that all I should do during the gym part of the session or could I take some additional lifts if I feel fresh?
