Designing A Six Day Per Week Weight Training Program. Help and Suggestions needed

With my current work schedule, I am finding the 4 day upper/Lower split I've been doing very difficult to fit in, and I believe it's hindering adherence. I feel like I may have greater success with shorter workouts (4-5 movements or movements I can easily superset) more often.

Fortunately, I was relatively well prepared for the covid situation. I was able to get 350ish pounds of weights that had been rusting in my parents basement, I have one long straight bar, one tricep bar, and 2 18 inch dumbbells. I have improvised a close grip pull-up bar from the keyboard mount of an old desk that I was able to attach to the outside of my balcony that's just a few feet off the ground, and can easily do dips on the balcony. I've actually been able to improvise ways to do a lot of exercises; on the whole I've been quite pleased. It's just feels impossible to fit in sometimes when I have like 2.5 hours total of commute on full work days with worsening traffic.

I was thinking of doing something like a full body/upper/lower, rest and then repeat with variations. That would give things like (dumbbell and light) deadlifts a natural place, and would let me hit upper and lower body 4 times a week each. To keep it short, I would have to rely on compound exercises. I would also like for it to be sustainable as I am very tall and would be doing it 6 days a week, so I would be avoiding things like heavy barbell deadlifts, but doing extra lower back work to compensate.

What I am looking for are good "bang for buck" additions that I could easily do based on what I have.

So far, this is what I am thinking:

Full Body A

-Heavy Dumbbell deadlifts (fantastic- easier on lower back, and I've been able to load my Dumbbell near 300 pounds so far)
-Dumbell calf raises
-Barbell Good mornings
-Weighted Planks


Upper A

-Dumbbell floor press
-Dumbbell one arm row
-Dumbbell concentration curl+ seated dumbbell tricep press (superset)
-Probably a barbell military press (I'm finding dumbbell shoulder presses to cause rotator cuff pain)
-Dips

Lower A

-Barbell hip thrusts
-Barbell hack squat
-Barbell calf raise
-Weighted Planks

Full Body B

-Light barbell deadlift with high rep range (like 135 to high 20s for a few sets)
-Light barbell calf raise with high rep range
-????
-????
-Maybe some cardio?

Upper B

-Pullups (weather permitting)
-Tricep bar bent over rows
-Tricep Bar Curls+ tricep bar military press (both together as one rep, this has hit forearms and shoulders surprisingly well and is a great time saver)
-Tricep bar standing tricep extension + barbell curl (superset)
-Dips with more chest focus

Lower B

-Light barbell Hack squat with high rep range
-????
-????
-????
-Maybe some cardio?

So yeah, if you have any suggestions to fill in the gaps here, or omissions that you believe are well worth the time, please let me know. I find worthwhile leg work at home to be challenging. I'm open to anything I can do. By the nature of my work, I don't think I'm going back to a gym any time soon. Just gotta make it work.
