I started at floor 1 with 5 swords all lower than level 15 (2 tantou, 1 tachi, 1 uchigatana, 1 yari), and a kiwame Hakata lvl 33. The baby swords leveled up as I played and I was able to get to around floor 38 before the tantous started taking damage. I swapped them out for non-tantous around the same level as the rest of the team (they had grown up to around level 40~45 by that point). I'm at floor 41, and all the formerly baby swords are still doing just fine.

So, basically, your swords will level up as you go, I think you should be able to reach at least level 50 if you go for it! Tantous might struggle though, so maybe only bring Hakata if you have him.
