sorry I'm just curious but will there be a tech nerf on it?
also like for ex. if a certain faction would SRP for it would they be able to use anyship? ex. Libertonian faction using rheinland technology and ships?
If it's part of their SRP - yes. SRP must specify which ship you want to use (unless it's a general permission, for example an SRP for free usage of Liberty Snub ships dunno). You can't change your gear to anything not permitted in your SRP request approval and if you do - the SRP can be revoked.
