Sure, but you probably also have a good idea of what your audience (players) will tolerate and appreciate. WotC has to deal with a lot more uncertainty in that regard, and as we have seen time and again, them getting it wrong even in one instance out of 100 is still an issue. And, frankly, the real problem with "historial" settings is that by and large, they aren't. They are based on outmoded, ignorant, just plain wrong pulp fantasy interpretations of history. And even when they aren't, they are based on history written by people with biases and agendas stretching back centuries.
That is to say, for WotC in particular but most publishers, trying to incorporate history into their fantasy worlds in just too little risk for too little reward.
