Is it possible to clear out bunker bravo using grenade launchers? (for the most parts at least)

Probably looks stupid as it is but I'm dead serious. I've already been abusing the repair bench at the gas station which even though requires real money, you can just buy like the cheapest thing from the store every week and essentially restore them forever. I have 16 of them right now, one always at bunker alpha for frenzied giants and 15 at the base to use however i want, and since they're repairable i figured maybe put them to an actual good use, so has anyone ever tried this or am the first one?
