Been trying to track down some of the circle/group works, but I just fail :P
I would even go as far as ordering the ones with conversion, provided I could find a site which did international shipping.
If I recall right, MelonBooks still has an no no stance for outside Japan shipping.
EDIT:
Few more evil conversion ones from the same artist. One of them is guy to a girl -> then evil.
Hopefully not breaking any rules linking them in this thread, just thought it didnt have enough
merit for its own thread in TG section.

So much good evil conversion material is lost due to them being short novels.
EDIT 2:
The style seems pretty similar to this chap
http://uragiri.sakura.ne.jp/index.html
They could be part of the same circle/group or just somehow connected.
Time to go finalize my order for that Dark Mercury doujin, I'll be sure to give scanning it a try once I have it.
