I'd Like to See Imitater as a Plant in the Game

So, I usually run into a problem mid to late into a level, where I produce a lot of Sun and cannot place Plants very much due to some of their recharge times being slow, further leading into a lot of Sun I want to spend, but can't.

I believe I can solve this problem via adding Imitater and giving it its own dedicated seed slot, which effectively allows you to place a given Plant already in your current roster twice at a time. An imitated Plant will be signified by being gray-scaled and will behave exactly like the actual Plant of the Imitater's current level. You can still merge the imitated Plant the same way as its actual counterpart, too, as the resulting merge will be its imitated version, behaving the same level as Imitater.
