Different registration form fields for each Prestashop multistore

[PrestaJunior]

Hi, 

I have a Prestashop with multistore feature active. 

Both shops are different and I need custom registration for each of them. 

Each registration page will contain different form fields, so simple HTML/CSS would not work here, as the POST data need to be stored somewhere via controller... 

I tried to override /classes/form/CustomerFormatter.php but it change registration content in all shops. 

I also try to create custom module which override above file but only for specific multistore ID and it do not help. Same results as above. 

Do you have nay idea how to create different registration form for each multistore shop?
