use an alternate game client

[phacemeltar]

i was wondering if at anytime in the past 15 years, someone has attempted to remake the titanium client? the current titanium client is very bulky, uses some outdated code, and is relatively unstable.

since most of the content comes from the server, would it be possible to make a custom client without getting sued by Sony? also, how hard would it be to make a client that could communicate with the game server?

i was thinking about this last night and it would be cool if there was a version that had a smaller RAM footprint, loaded faster, had updated graphics, and also wasnt illegal to distribute.

thoughts?
