Here's my thoughts:

1. It wouldn't make any sense for Lexa to be the Commander of all the 12 Clans permantely. The 12 Clans used to be at war with each other (so, it's not like they had the same leader if they were fighting each other). The Coaltion was formed. The Coaltion brought together the Clans and formed an alliance between them. However, it's hard for me to believe that the 11 Clan leaders just told Lexa "You can be in charge of our Clans" and just hand over their Clans to another leader.

2. I agree with you about Lexa being the Commander of the 12 Clans just during the war with the MM. Lexa (along with the Sky People) knew the most about the MM and Mount Weather, so it would only make sense for Lexa to be in charge of the other Clans until the war was over.

3. I have seen Kim (one of the writers) confirm that Lexa is the Commander of the 12 Clans. However, she never specified if Lexa was the Commander of all the Clans permantely or if she was just the Commander of the 12 Clans during the war with the MM. I have also seen Aaron (another one of the writers) say that the Ice Nation had its own leader. Jason did say (in older interviews) that Luna was the leader of the Boat People. Lincoln told Clarke and Finn (in WAGP1) that Luna was the leader of the Boat People.
