Well, I dont know if I've understood it right, but...

Max 4 bone weights means one vertice can have 4 bones moving it around, right?

If thats the case, it could work. I dont think it'll need more than 4.
But I have no idea how the model has been made. It costs a LOT of money, so I cant test it before I buy it...
