I really like
Conall and
Conri - I had not even heard of these names until just now and they're really cool.
Sullivan is another one of those surnamey names, but as far as they go, it's a nice one. Not bad, but I wouldn't use it.
I would agree with you on
Conri's pronunciation, but do you think
Conall could be pronounced CONE-all? I have no idea, just wondering.
