Yeah, my point is that you're gonna have to try make your own. I don't think there are any beehive tiles. Atleast not exterior, indoor I believe kyledove mode some (though not sure if they were public.
As for your question, yup. I'm working on something called Celestium. :D
A giant beehive....hmmm. You mean like something the player could enter? If that's the case maybe you could edit one of the battle tents in R/S/E 's battle frontier. That's somewhat of an 'unique' idea so I doubt you'd find many sprites (if any) of it.
Sorry for the extended absence...Our internet went out for a few days, so I haven't really been on Pokecommunity for a while. I guess those few days offline have broken me of my Pokecommunity addiction
