Without random encounters you only need to worry about bosses, but if you make a few runs through with your main party clearing the bosses then Mog party can eventually fly through without any trouble. It's a little more time consuming, but generally not as boring as leveling a third party.
Once I check the dungeon's layout again, that might make more sense. I thought everyone had strictly isolated routes?
They do have isolated routes, but if you dump all your best gear on the weakest party, even they are gonna be able to defeat the bosses. Also, you can at any time go back to the ship and regroup, without any of the bosses respawning. So is there is a boss you absolutely cannot kill with your weakest party, go back and send your best guys at it.
