Question: WK , MCR Charging Handle Track Rubber Dust Cover, like SIG 556, Possible?

At time index 9:53 of YouTuber Brandon Herrera's video on the SIG 556, he notes the gun has a split rubber dust cover (which he refers to as "weather stripping). The charging handle slides through the split between the two halves of the cover (I've seen to them referred to as "dust lips") , and then the two halves close up again once the charging is back forward.

Would this system work if a WK and/or MCR were retrofitted, or possibly a high end (Brandon refers to the dust seal as boujee) version was created (something like the TNA upper comes to mind)? Or would some kind of actuated door, like the one on the ejection port of the TNA upper, be a better option?

I bet that would be easy enough if a guy could track down a silicone rubber type manufacturer, would def want to order in quantity to keep the cost down. Some kind of 3M adhesive would work well to attach it. I'm thinking it would hold up well as the adhesive velcro I've used for shotgun side saddles has always worked great. I would consider it a semi consumable item/wear part.
