Would it though? You would need two scenes for every interaction with her, one with dick, one without. Would change a lot of other characters interactions also. Without, suddenly the homeless paralegal now doesn't have the stepping stone dick before she takes the bigger MC dick. Unless you just really scrapped the entire use of the trans dick, even the DP scene, from the have option to make it so similar to the have not option. Basically making it just a decoration, rather than anything sexual.
I may be wrong but I imagine there is a whole huge section of different renders and dialogue between the trans/not trans Shauna options in WVM. I dunno for certain, as I chose to make her biologically female(see my dick hate posts elsewhere) and have not tried the other path. I still would have played it if they did not give us that choice though but you give it to me, no gonna be a dong.
