don't remove GC from that server or you'll break exchange; it is dependent on GC
definitely make the new DC a GC; no harm in having more than one

don't recommend doing anything at the AD level on that box while exchange is installed due to the risk involved.  get exchange off there first before changing AD in any way on that box
