Why would you pay a performance penalty? I'm assuming that one node using the IP link will advertise itself as a child of the other (e.g., you model the IP link as a hop of low cost). To some degree, it's as if you set up another CTP tree whose root advertises a non-zero cost. The two major differences in behavior would stem from the fact that its cost is variable (so more loops are possible) and the CTP hysteresis value for link change being a constant (15) means high cost routes are more free to change next the next hop.
