Would allowing players to have "action glamours" not achieve a similar effect?

Like, if I preferred MNK's Bootshine to Leaping Opo-Opo (or, good lord, DRK's old Power Slash over Souleater), I could simply select that in the menu or even an option that randomizes which animation I'll get similar to how our characters shuffle through various /cposes while idle?

The only knock-on effect from this would be that certain actions have different "impact" times (the time which the damage or effect is actually dealt over the course of its animation), but this hardly ever matters outside of very niche things like speedruns where that sort of timing can matter.
