Maybe play a different game for a day or two each week: stud, draw, H/L, etc.

Each game puts weight on different elements of poker, and has generally fewer pitfalls to avoid than NLHE (which has fewer pitfalls than Omaha).

I learned a lot about position and keeping sharp table awareness from playing 7-stud H/L. It's not for everyone, I grant, but I even appreciate the triple draw games like badugi. It's still about putting villains on ranges and odds / outs, but the focus is shifted a bit.

Playing similar games sharpens your insights into both.
