Here's a very easy way to create a mount for every crafter:

Make a carriage as a base mount. Now attach different items to it depending on the crafter.

BSM? Attach some existing weapon sprites to the carriage/cart.
ARM? Attach some Armors/Armor parts to the carriage/cart.
And so on and so on. They could basically make one base model, and then just add already existing objects to it. That way they can basically create 8 mounts with little effort and I'm sure people would still be excited over it.

I'd really love to have a little Carriage for my BSM with some weapons attached to it.
