A couple of months ago I've made myself what I call a tape cover, just 1piece 1 1/2 inch long mono porous, vertical from nose to chin to help lips close (I know you don't like to tape but that's not much),
If you look at the picture, you'll understand. Easy DIY cheap ($) effective, for me 25 out of 30 days -0 leaks. ( last 2 months)
What you need: 9x12x1/16 foam from any hobby store (Micheal's ....)
2 pieces of material: 24 inches x 3/4inch ---- 3 inches x 3/4 inch (material that don't stretch)
My wife gave me a metal strap adjustment from an old bra.
or make one from a paper clip or a piece of wire.
2 velcro ; 1soft 5 inches ----1 hard 2 inches .
Cut 2 pieces of foam, mine are 4 1/2x 11/2--- cut a little knoch in the center (not to interfere with the mask) --super glue together--sew the material on each side.
Sew the metal clip at the end of the 3- inch attachment. Slide the 24- inch in the clip. Check the picture to see where to put the velcro.
I've made it that way for 2 reasons; all you do is slide it over your head.
easier to adjust the tension.
Same as a mask, you do not overtight- tight enough but not too much. If you drool wrap a cut- to-size kleenex tissue around it, the tissue will absorb it. For some reason, with or without the tissue if it is attached right there is no leak.
In a hurry to take it off, just drop your head to your chest.
Choose the measurements as you wish, the ones I gave are for my face.
I know it's another thing in your face but it's small, easy to put on, and not hot like a head cap or a chin strap & hopefully, if you decide to make one it will help you.
