Several threads lately brought this idea on.

I'd like to exchange boosters I don't like (but it could be any booster) for gold bars. 1 booster = 5 gold bars (or whatever players think is fair). The idea is similar to Pokémon, where players can sell items in their bag for money in the PokeMart.

Alternatively, getting rid of the Swedish fish booster altogether would be worthwhile. That way I won't have to scream every time the spin wheel lands on it, as it so often does. grumble grumble

It is the single most useless booster in the game, liked by only Tiffi I imagine, and wastes space on the spin wheel. I currently have 2,175 of them and have no intention of ever using them.
