Harmony - Troop Symmetry

Is it possible to make the second alternative Specialization available through either Summoning magic or Machines?

For the Elves, it's done through summoning.
We were discussing this today here: /topic/8688/

Essentially, based on what I described in that message, the following changes are proposed:
- The Summoning skill is removed from Gnomes and given to Elves;
- The Machines skill is removed from Orcs and given to Gnomes;
- Logistics is removed from Elves and given to Orcs (through the "Path of War" and "Aura of Speed" perks).
All these shifts are necessary because all skills appear twice as core specializations leading to a Specialization (i.e., Light for Humans and Elves, Attack for Demons and Orcs, Chaos for Gnomes and Tower faction, etc.)
