Yeah, I've overlooked hips before and weak hips to go with otherwise strong legs makes for a weird imbalance and some easy tweaks. I actually usually notice it in other places when my hips are weak because other musculature is called on to step-up.
I like Jay Johnsons
SAM routine. It includes some things similar to what you're recommending and only takes a few minutes. I try to get at it post workout or before going to bed 2-3 times a week and it does wonders. More concise summary than the videos
here. I usually just do one of the "Phase 1" or "Phase 2 Easy Days". Highly recommend trying it out, lot of bang for the small time commitment.
