Can you change into a different class while in another?

Currently, there is no limit to what classes you can pick, apart from having the previous one. So for instance, you could accept archer, infantry and cavalry all at the same time, however this would cost 15 class points and the requisite xp. So at the same time, you could also go infantry -> heavy infantry and use up 13 class points. We belive this will lead to a unique hybrid class system which should allow for some customized gameplay options unavailable anywhere else
