Fleece is rather clinging - I'd recommend making it a bit longer than knee length just in case it gets a bit tucked up, and with deep under apron pleats too - when lounging on the couch you don't want draughts.

More traditional kilt materials tend to be non clinging so the fabric opens out easily around the hem. They are quite dense too - fleece is low density so it will not fall or flow easily.

I am leaning more towards trying to talk you out of it the more I think about it.

How about finding a good quality duvet cover - king size, and cutting each side into three strips and a waistband?

You could then make two reverse Kingussie kilts, no need to sew the fell, just the waistband and hem, sew on a couple of buttons to hold it closed and then you could sprawl about as you pleased with ample coverage at all times and angles.
