If you'd like Freestyle to provide these films (Fuji Acros 100 and Neopan 400, and Kodak Plus-X and Tri-X respectively), you should contact Freestyle to let them know your interest. Here's a reply from Freestyle to an email I sent re. these potential products:

"Thank you for your E-mail. I have passed it on to our Marketing
Department for evaluation. If we receive enough positive feedback from
customers like yourself we should be able to add the 120 & 220 sizes to
the line if the manufacturer can supply us a competitive price and
quantity.

Customer Service & Consumer Direct Sales"
