They would have to restructure the entire game if this was to be implemented. UI would have to be changed, gear stats would change. So many things. I'm not sure this is really feasible. Remember a large portion of the STS market is younger children. Can't make it overly complicated for them. I like silents idea. Each class has its own second spec. But really that already exists anyway's. Combat engy, healing engy, destruction op, solo op, tanking comm, dmg comm. Just depends on what skills you choose.
