Thoughts on switching from 5 day Push, Pull, Legs, Upper, Lower to Push, Legs, Pull, Anterior, Posterior?

I’ve been doing Push/ Pull/ Legs / Rest / Upper / Lower / Rest, but I’m considering switching to:

Push / Legs / Pull / Rest / Anterior (Push + Quads) / Posterior (Pull + Hamstrings) / Rest

I want to keep the exact same exercises, weekly volume, and sets as my current routine and simply rearrange them into this split.

The main reason I’m considering the switch is that my Upper days are getting too long and fatiguing. I also feel like it might be better to spread my leg training out rather than having two full leg days — basically 1 full leg day + 2 half leg days.

What do you guys think? Would this rearrangement be better for recovery, exercise performance, and overall fatigue, or are there any downsides I’m overlooking?
