They're interesting.
Like you I don't know what the medic squad would be renamed to. I do use my medic squad for that .. . but at three people it's 180 manpower to do it so it's actually expensive and the models are pretty weak. But it's a good last ditch grab-that-now gimmick.
I don't like the assault upgrade though, Brens are LMGs so would never be standard weapons (and they're at the weapon racks anyway). And such as massive change of role from long to short range would be a funny transformation for a unit. I think the sapper upgrade fits the role better and the anti-garrison can be worked into it with the light gammon bomb. It's also behind a bit of tech.
I'm sure someone with a little more knowledge of Brits WW2 structure could come up with a name for a second line squad.
You can still play with the costs and values of the medics, but in practice people are using them to grab support weapons. If 180 is to much for a squad that disappears after it grabs that AT Gun/MG, you could further cut the cost and then move it onto the medic upgrade. I'm of the opinion they would get an HP Buff and Springfields in their base form, so they would be more in line with standard support teams which would account for some of the remaining cost as well.
The medics themselves would likewise get better, as you would never have to worry about accidentally bringing them into the field like you do now, and would require less babysitting since you wouldn't need to be constantly going back to base to fire off medkits.
As far as Assault upgrades for Tommies, iirc, most people wanted Royal Engineers to become stronger in the close assault role. If those AT sections went through, you could probably remove their AT Grenade for smoke and try and buff their close assault more while dumping the IS Assault Upgrade I mentioned.
