Well, yeah, but...I suspect there are a couple of problems here:

1) I have no idea as to whether you could coat photographic emulsions using this equipment (I'll defer to others here, such as PhotoEngineer)
2) Custom=Expensive (No need for me to defer here - I'm on pretty secure ground with this one). I suspect this would be the sort of operation that would require a considerable cash advance.

I'd hate to have to front Agfa, say, 1 million EUR and then have to charge $20 USD for every roll of 120

FujiFilm also does this sort of thing. If EK does it, I've yet to learn of it.
