I would love to see SWTOR on this access it would bring more players to the game with a one stop shop for everything and this would include a sub but no monthly CC allowance. Once and only if this comes out i'll be signing up for it.

I would not expect it to become part of EA Premiier or the ability to not get monthly CC Allowance. The CC allowance is a reason why many do subscribe to the game. They would probably need to redo the launcher to use origin launcher which I do not see a high enough ROI to justify the amount of work needed.
While it's possible, I don't foresee it happening soon or anytime in the future.
