They would be stupid
But can they add something like that without breaking the game increasing the amount of data overhead for multiple new characters elements
Or who knows that value is a hard stop at 8 for all races.
I assume the possibility of something else breaking downstream if they added new models is the reason why they announced it so far in advance, so they'd have appropriate time to sanity/stress test it over the course of a few months. I mean, if what Thorny is saying is true, the process for new model creation can't be that complicated.
Now maybe the interface is super dated and someone has to take time to learn how it all works. Wouldn't you be getting that time/cost back hundredfold from people who want to change up their look? People with bad reputations get to instantly start over via name change/server swap and race change. Literally tens of thousands to be made, then you throw in the FFXI lifers who are tired of being whatever race. Literally printing money here.
Makes no sense to make race change if they're not pairing it with at least a couple new models
