Well MLP, I'v got no idea how good yuo are with scripting, but here are 2 ideas's that will sell:

A) Write an "ADU" script for Poser figures. Compatible with all.
Will sell 1.000 copies.

B) Write an "AUD" script for Poser figures. Compatible with all.
Will sell 100.000 copies. (and can be twice as expensive, will still sell in volume).

 

Oh, you did not understand ADU and AUD?

"ADU" = Automatic Dress Up script.
"AUD" = Automatic Un Dress script.

Other good sellers will be:
 
"V? Brew me some coffee", script will also do good.
"V? The dishes need done", will be popular.
