Yes, I have nothing against being in two clans, as long as the second is one such as 4 Riders or the Knights that are more of an "in-game" sort of clan. Ones that are the "best of VW" kind. It makes it harder to engage in clan wars with them, but I do not seek to fight with them.
Also, seeing as you are an acolyte, it is allowed. If you'd rather just be a Rider, there is nothing stopping you, though you have been a great addition to the Creed.
