Maybe. The only problem is that leads to very few avenues for creating a new job. The only time you'll see a difference is when you combine a DoW with a DoM. I don't really see a Marauder & Pugilist, Gladiator & Lancer, and Archer & Thaumaturge making any new job what so ever. It's best and far less complicated to just introduce a new job in future expansions like they did previously.
