To be fair, implementing such a path with a whole lot of new art and written scenes would take a huge amount of work. And I personally prefer Gomamon as a sub too, so there is that. xD
I have a few seductive more confident Goma Scenes. Not maybe really domming still, but as the game is almost fully written, I don't plan on trying to find ways to squeeze in more right now. In all honesty, I will be happy once it is all written and I only need art. xD
