Not possible in plain Half-Life. Unless you're going to write some custom code, which then means you'll have to put the map in (mini)mod format. But that's probably not worth the hassle.

Have a look at the Source SDK wiki, I'm sure there're some tutorials on getting started coding HL2 mods. If you don't know C++, you don't have a chance, though.
