"what if we had gym leaders for concepts rather than typings"

Not sure if this has been brought up before but after looking at paldean gyms break the leader norm I was thinking it would be cool if we had gym leaders for concepts rather than typings, for example:-slug gym (I got this one from a twitter post today): Magcargo Gastrodon Hisuian Goodra, Shelmet-cotton gym: Wooloo, Eldegoss, Altaria, Whimsicott, Jumpluff-pink gym: Clefable, Wigglytuff, Blissey, Audino, Lickilickyturtle gym: Torkoal, Dreadnaught, Blastoise, Shuckle, Turtonator, Tyrougaand things like this and so on, interested in seeing your ideas for these so id appreciate to post some in the comments via /r/pokemon https://ift.tt/cgNn2Ff
