I don't think that would be a good idea. It's complicated because you would try to make a lots of effort to make that friendship work... but unfortunately soon or later he'll decide to move on and that will hurt you a lot..
Its senseless, risky and sign of insecurity to still want ex in life. you don't need ex as a friend... all you need is some sense into you.

I don't believe feelings are always there. Once I accept a relationship is over my feelings fade... until they have gone completely.
I'd never stay in contact with an ex. It just complicates future relationships , and brings about too much drama into your life. I'd never put a new SO in such an uncomfortable position. I'd view it as disrespectful towards him. He'd be my priority , not an ex. My ex would have no place in my life or future
