I'll look into it, the idea seems pretty valid as many items have reached rarity due to not being re-introduced, where the item wasn't meant to hold much collector value. The one issue, which has been addressed before, is that these items are rare now, collectors have paid hefty amounts to have them, and people that use these items have usually paid even more.
I'm pretty much the one responsible for re-introduction of legacy items, and I tread lightly to not harm anyone in the process. The safest route is by throwing these items into the premium BP, as there is a paywall and the numbers tend to be more limited in return, but obviously there is no "right approach" as there will always be someone that loses out/gains in the process. One thing is for certain though, items of real rarity won't be restocked, the only option is to make a new version which doesn't affect it's current status.
Always open to dialogue keeping thread open in case anyone has any questions/opinions.
