You mean make both available? Sure. The only decision you'd have to make is whether Magery (Ritual Path) and the Path skills had to be bought twice or were shared between the two core skills. If you choose the latter, note that it makes RPM casters even more versatile (since they need only buy a single extra Hard skill to have access to a new, more stable form of casting), so you might want to tack on an Unusual Background of some sort.
