Working toward Cenotes
A very low volume mask might help, that air does float up your head. They are easier to clear as well.
Moving some weight to shoulder straps, or taped to very top of plate, might shift it enough forward that you can restore some to your belt. Weights on you top tank band might be close to neutral with respect to trim. AL plates are nice for the ability to put most of 'their' weight where ever you want it.
Agree no ditch-able should be fine with so little total weight. Though dropping a belt is easier than getting out of and dropping a rig.
