I'm still thinking that it would have been the better option, to remake the entire game in a 3D engine.
And yes, I am actually considering to do that myself, as an experiment / learning project in Godot.
But, if I go for it, then I would definitely save any work related to the visualization of the girls to be done last, and most likely not bother at all with the old models.
It would probably be more interresting to use new models and to make them interact with the enironment, like sitting on bed, on the floor, at desk, etc.
The main advantage of remaking the entire game would however, be to have nice fresh game world, which is not stuck with Vrens, early design choices, such as for example 5 time slots per day, where all actions either take no time at all or several hours.
If that was replaced with time, then chatting with girls would take time, not energy. And having sex would require time and energy, making it impossible to give a girl 20 orgasms in 0 seconds, while the next one is waiting.
But, I will most likely, either find my self too lazy to do it or give up half way through
