The feed into (most)panels is aluminum wire.

Aluminum is not the problem, per se.

Simply changing the amperage of a breaker, up or down,does not guarantee appropriate protection for the circuit; the AWG must match accordingly i.e; 12/2 or 14/2, etc.

As far as GFCI protection(wet location), everything downstream from a GFCI receptacle is thusly protected. Redundant installation can interfere with that.

Arc fault protection may be more appropriate to your needs.
