Speaking of air cleaners…

Okay, so I don't know if this is a really dumb idea… LOL, but why couldn't I find a common air cleaner and clone it into a 1970 "340" air cleaner? I mean couldn't I cut off the air horn (or both of them) and get somewhat of a similar looking air cleaner?

Have any of you done something like this ? I'm not thinking for show quality, but just a decent looking, functional part.
