I need to install a 50 amp breaker for an EV charger in my fuse box. The problem is that the box is already full. I was wondering if I could replace 4 QP type 15 amp breakers with 1 quadplex breaker, or something else. I was thinking I might be able to replace them with a Q21515CT2 breaker.

Each 15 amp breaker takes 1 space, so if I could consolidate them somehow, I would be able to fit the 50 amp breaker.

FYI - all of the spaces where tandem breakers can be used have already been taken.

Here is a picture of my fuse box. I was thinking I could consolidate the 15 amp breakers on the top right.

Here is a the breaker I am wanting to install:
