In the StarCraft II Galaxy Editor, how can I create a watchtower that provides vision of another area than itself?

Question

I want to create a watchtower that does not provide vision of itself when captured, but rather a completely random unrelated part on the other side of the map. Also, can a map still be a melee map with such a radical change to a watchtower?

Answer 1

This is untested pseudo-code, so it probably won't work right-off-the-bat - (I used to use the BW map editor)

Reveal map trigger

Events
    Unit - Any Unit Enters Within 2.0 Of Xel'Naga Tower (30, 100)
Local Variables
Conditions
Actions
    Visibility - Create a visibility revealer for player x within region
