It won't work on observers specifically, but if you cloak a unit by disabling and re-enabling it, and the player controls no detectors, then the unit will appear uncloaked but the game will consider it cloaked. You will not be able to select it or target it.
I can't seem to find the wiki article on this particular method of cloaking, and I don't recall the units that don't crash when performing it ...
EDIT2:
But fortunately I keep these lists around! All heroes omitted. They work the same as their normal counterparts. It appears that some unique heroes are missing (such as Infested Kerrigan), but this list is old so I wouldn't rely too heavily on it.

There seems to be a lot of variables, like direction the unit is facing (I think this applies to Battlecruisers), perhaps tileset, and even more that I don't know about. So I'd say try ones that it says crash if necessary. You may be lucky.
If you need an overview of the method I'm suggesting, the trigger is like this:
None specified.
None specified.
Create a unit in a remote, unviewable areaDisable doodad state (can only disable or enable one at a time ...)Wait (any amount of time will do, as long as it is at least one trigger cycle. DCs work as well.)Enable doodad stateWait (again, at least one trigger cycle)Order unit (to clear any invalid orders or invalid unit frames)WaitMove unit to desired location
