Mine is still on, but it's only four screws holding it on that pierce the mask so I imagine you could stick some orange or black rubber plugs in there and it would look neat enough. or just leave the holes open - nothing unsightly about that IMO. i think the easiest way of accomplishing your goad from a practical standpoint is to put those white plastic butterfly anchors in the holes so you can easily remove/attach the screen with wood/sheetmetal screws. Glad I thought of that. Going to do it tomorrow!
Frankly, I suspect the turbulence on the hwy is better without the touring screen. I'm 6-2. Have yet to try it though as I bought the bike with the screen.
