I went through 6-4 just fine without an Oodachi. My team composition consisted of 6 wakizashis (coincidentally the same as yours) and two tantou (Imano and Midare). While they're a bit too low leveled at the moment, continually train them on map 6-3. From calculations, 6-3 grants the most experience from nodes A-G, go any further and you'll encounter those pesky yari. Those nodes also have an extremely low chance of encountering Yari so you'll spend less time repairing swords.

Once they're around 90, eqquip them with long ranged troops and hopefully they'll knock out some of boss' troops and if you're especially lucky, you might get a chance of killing off the yari. Waki's are the best choice for 6-4 due to their high critical hit ratio (impulse). There will be a good few times where they'll push the enemy back and you'll escape with an A rank, despite not killing off all the enemies.

Hope this helps. Persevere and you should be able to do it!
