Keep in mind, I don't have any idea of your flow timing, here's one idea to consider and if you have the equipment to play with. At the end of your less desired flow, pull the queens (Mel Disselkoen's ots method), hive them and the honey you don't want with them. Install new (or spin out some of the filled ones, you can feed it back to them later) comb on the queenless hive for the new flow, you now have a month for collection of the good stuff!
