Since Commando Regiment is overburdened with expensive munition abilities you could exchange at least one ability with a different Commando Glider drop. This could be either a longer ranged Commando Squad with an optional recon role or an AT based Commando squad. The AT based squad should leave the gilder fully equipped with PIATs. To give them some more uniqueness they could be PIAT experts (similar to AEF Bazooka Elite troops) and have an additional ability like vehicle detection/vehicle button/heat grenade/(placeholder for another AT ability you may think off)... Just some ideas without any thoughts about balance, which has to be considered carefully of course.
The problem with Glider insertion is that it takes so long to land that you're never going to use it in the heat of battle unless you want to YOLO the glider into a backlines repairing tank, which I don't think will be very useful. If anything I think some kind AT Infiltration Commando (like current AT Partisans) would be easier to use but it's also kind of clunky to have two separate Commando abilities. I think the cleanest implementation would be to have some new passive "Commando Anti Tank Training" that gives them Elite PIAT passive, maybe the PIAT Upgrade that doesn't require territory, Sticky Heavy Gammon bomb/whatever. Smoke Raid could probably go but I don't think balance team would do it since it's kind of the whole flavor of the doctrine.
