Can you splice them? Yes. Should you splice them? No.

It really all depends on what your over current protection is. If your #12 wire is on a 20 amp breaker, your #18 wire can melt and cause a fire without tripping the breaker. I do not know what is the amp rating of 18 gauge wire. -- Sparkfighter
