RRS Auxiliary battery upgrade to optima

Hi all,
I am looking to replace the start stop battery with a larger optima yellow top, the goal behind this is to be able to use it as a AUX battery and run accessories such as a fridge etc.
can i just remove the stop start battery and install the larger yellow top and still have the stop start function ? will the current system charge the larger battery? is this even possible?
I cannot put a second battery behind the LHS panel as i have the rear A/C unit in the and have no space.
