I know it's not exactly the same kind of thing as you're suggesting but I'd love it if they introduced an elixir to apply to a house so it acts as a plant like, the same way the Red Barn Farm or botanical Gardens do. It would certainly be worth buying for areas with plants so we can do rotational harvesting and re-plants :)
I like your idea too, but I'd prefer something a little more permanent if it was a crowns item. If it was for gold it would be awesome for people with lower access to crowns or not needing it all the time. Having both would be perfect so we have options to suit our needs and budgets :)
