Sadly, that isn't possible unless a dungeon were to be recycled- as it is currently not known how to create dungeons. You may do this yourself if you'd like, however this would mean scrapping Freedom Coast. You can fashion this dungeon off of nectar meadows, a dungeon featured within super, which had either hero/partner face off against 2 beedrill & 2 combees. Similarly, it is not know how to import custom tilesets without completely reverse engineering the game yourself. If it means anything to you, you may edit your starters to be either vespiqueen and combee, then recruit an additional 2 more combees.
