Well, probabily Sona like Seekvaria could be nto happy to see Vali bacause he was a terrorist. Sona has little patience with people that think don't be punished for their actions. Vali for don't have interest for the woman( maybe he have little affection for Laviana), and the other reason is Saji: Saji probabily could challenge Vali for Sona, Vali should think that Saji only figth him not for a girl. So for now we just wait if Vali and Sona in the volumes could have more interaction... Your points about their similarities is correct, but I don't think that this will be the plans of Ishibumi about Sona and Vali.
