Yes. Command C on the look you want to shove somewhere else then select that 'somewhere else' clip to paste attributes via 'Command Shift V'. It'll show a selection of the attributes you can deselect if you don't want all of them applied to the target. Entirely doable across projects or libraries.
I use adjustment layers and rename them as a way to keep track of adjustments or effects instead of digging through things on the clip level. Final Cut has such a Neanderthal way of notating or identifying things compared to Resolves' bouquet of label and coloring markers & clips. The adjustment layers can be independently bypassed to determine which look is the one you're after keeping in mind the effect is applied in the order they're stacked.
