Disguise, via Mechanical Critter?

[Soup]

I have a general interest in being able to give a unit neutral invisibility through having a passive ability that bestows the same effect that occurs when a mechanical critter is summoned, in that other players see and treat it as a neutral unit, rather than player owned. The painful bit I'm finding is getting it to applied to a unit with an ability, rather than a unit summoned via the mechanical critter ability.
Any information or help on this would be greatly appreciated, thanks.

I think it might work if you transferred ownership of the unit to Neutral Passive, then granted the owning player control over the unit.

you may not give control over individual units this way...

try chaos morph, may be it will work.
