I'm assuming that plan is for World 3? It should be fine as long as you're still within the level range to get experience for the maps. IIRC they're only up to the low 30s, so I'd check on that.

You can start worrying about uchi/tantou/wakizashi leveling when you want to get started on World 6. The recommended level for them to fully clear the map is 60-70+ though, so you may want to get started early.
