Want to change Retainer's appearance

Hi guyz,

I want to change Retainer's appearance, i.e. He is male lalafell but want to change to female Roegadyn.

There is an option to release retainer but I doubt if I will loss all items in that retainer.
I can't transfer items to another retainer or keep in my inventory bcoz of not enough space.

Any thought ?

Maybe temporarily storing those items into the Free Company Chest...

I think I read a while ago that you will be able to get a 3rd retainer in this next patch. Maybe just wait until then and make your 3rd one a Roegadyn.
