Had a chat site that had real doll private sexchat for a while - it was kinda popular but I think in a one-time kinky way... I think there's a market for it.
I would say do something about the eyes - wear shades, get them to look closed sometimes - otherwise it looks like corpse fucking.
And if Alexa is any indication the surgery site is somewhat popular on pageviews
http://www.realdolldoctor.com - and there used to be a blog about "me and my sex doll" (with a realdoll) that featured realdoll cumshots, titfucks, pov and all that... but it seems gone now.
You might have the corner on a exclusive niche. Then again, you could be working your way to a realdoll garage sale lol.
