Are a Gemini-Rooster woman and Libra-Pig man a good match for marriage?

Also, what is the maximum and minimum age difference between the two for the best understanding and communication? I have searched for a Gemini-Rabbit, Gemini-Sheep, or a Gemini-Pig woman without any luck. Maybe the best possible compatibility matches are not in my future or maybe my Libra-Pig over analysis is keeping me from making a bad compatibility decision. Please advise me. Thank you very much!
