with the whole opposite infection biomes becoming available without world hopping via the Dryad selling the opposite seeds in a graveyard. you can acquire that opposite biome key but there is a problem
you can't use said key so effectively you have to beat plantera in a corruption/crimson world which is time consuming
So i suggest adding in biome lockboxes that can be obtained from that biome's hardmode crate with a 25% chance of dropping. These lockboxes much like your shadow and golden lockboxes can be opened using their respective key once Plantera has been defeated.
It would also allow for players using pre 1.4 worlds to acquire the Desert Tiger Staff and allow for players to obtain said biome weapons with new modifiers without paying a platinum from a greedy goblin
