This is funny because I've been asked to bring back a character and was just looking at that.
Ina very short lived follow-up campaign in 2019 to a concluded campaign, me and oen of the other players were playing brother and sister who was the child of a prominent moon druid NPC from the first campaign. My older sister was also a moon druid, so could wild shape, and as the younger brother I never managed ot do it all the way - but part of Totem Spirit was "At your option, you also gain minor physical attributes that are reminiscent of your totem spirit", so with the DM's permission I made that happen but only when raging - so I "partially transformed".
Anyway we're starting a new campaign in the same setting and have been asked to bring that character back, but I need to de-level and remake him. And since then we've had the Path of the Beast come up which is pretty easy to work as a Wild Shape Barbarian. Limited shaping, but still the concept is there for thematics.
