You can train them, with some of your other swords (depending on you and their respective levels), in 2-4 until all of them are 30 and above (or just 20+ if you don't mind the chances of losing a few more troops). If you can max out all their stats by then, you can just grind in the first two nodes of 6-1 until they're high 40s or 50+ before trying to clear the whole map.
