"HuggyBear" said ...I beliueve it can be possible seeing as last time I checked that out they was allowing users to share their mods and letting people to mod their stuff.
I haven't played legitimate 3D Sexvilla in ages, but I can say without a doubt, absolutely not. They're files are encrypted and not very mod-friendly. They're business model is to sell you additional models/rooms, so it would be contradictory to their way of making money. With that said, I do know of a hacked version that has a very good mod/support community. They've managed to expand the game beyond what the original developers intended by leaps and bounds. They've even managed to mod Mass Effect's Tali helmet, EDI hair/visor, and Star Wars' Twi'lek head tentacle-thingies. It would be best to ask that community to see it's possible. Their faces are based on the same engine that Oblivion uses, so they look very generic and pudgy by modern standards. I won't mention the dev team's name or where you can download it, to protect both, them and DigitalEro because it is a hacked game afterall. AND I ASK ANYONE WHO IS FAMILIAR WITH IT NOT TO MENTION THEM BY NAME OR POST LINKS AS WELL.

Call me clueless, but what exactly is sexvilla? I can already guess a few things by the name ;)
