Can I play OpFor + Blue Shift with classic weapons/no separate m16/mp5 without grenades?

Title is my question. Can I play blue shift and opposing force with the classic weapons, and not sven's custom ones? As well, I want the smg to shoot grenades again, not spawn a weird HD m16 as a separate gun to shoot grenades, and classic sounds too.

Yes and no.

No - these OP4\BS maps doesnt have Angelscript classic mode set up.

Yes - If you are willing, you can try modding these maps and their configuration files but it'll take some time AND it'll be kinda pointless due how quickly maps gonna change, as these maps are not merged together.
