Good idea, but too bad theres only 4 units in the whole game that stim (marine, firebat, and hero forms). Hmm you could make a weird defense where you have to cloak all the units. And to make it hard you keep randomizing which type of ghost comes out so you can't do ctrl+right click on one and just press c. You have to click and drag... a lot. (>.<)
Also, to make it interesting, there are multiple checkpoints on the ghosts' trip to some place where they lose all energy and regain it so they uncloak, so you have to recloak them again while cloaking the ghosts back at the beginning. Just a thought.

Problem with recall is it takes a moment to take effect, and retargetting it negates the previous one you cast (unless it's with another arbiter).
This actually isn't a bad idea. Most people I would think could handle with 2 or even 3 hotkeyed units and constantly switch between them. It's also convient that the hotkey for recall ® is close to the numbers 1, 2, and 3 (these usually are the hotkeyed numbers I would assume) so one hand can focus on moving the mouse and the other can change units and recall at the same time. The game wouldn't be as bizarre as you think. <(^.^)>
Edit: Wow.. you learn a new thing everyday; if you put R in () you get ®

and about the stimmable units, you could also use like a dswarm or unload system and whenever you cast it over a unit it will cut its hp, it would give the same effect as stimming, and you could have as you said before, a lurker at the end with like 1 attack to kill it.
over a location where if the unit reaches it without dying then it subtracts like
the O is the lurker and the place where if the units reach then they lose a life, and the - represents the lurkers attack range.
