You can come up with something like that, but what will the result be? Such a development is only useful if there is an Orc opponent. Otherwise, it just takes up a slot and provides no benefit.
Haven't tried it, so don't judge. If it doesn't work, don't judge it right away. Maybe the reason isn't a bad tactic, but a bad... Well, never mind. And, by the way, the whole point was about a scenario against an Orc!!! Did you even read it, or did you just skim it and write something random?
Bow down and hear our cry,
Our earthly rulers falter,
Our people drift and die,
The walls of gold entomb us,
The swords of scorn divide,
Take not thy thunder from us,
Take away our pride.
G.K. Chesterton: English Hymnal
