I hear you. It's tough though. If it is the Queen and I wait another two-three weeks, I am way behind. If its not the Queen, assuming ( I hate to assume ) the new Queen is a perfect fit, then I am only behind 3-4 days. I think I will wait one more week and see how everything shakes out before I pull the trigger.Honestly, I cannot see the rationale for disrupting things. You have brood, and loads of it by the looks - this is a good thing. Requeening will add cost, time in laying, stress, and the possibility that she may not be accepted or have issues her own.
Outside there being other issues under the surface, does that outweigh a brood pattern's aesthetics? I do not think so.
Then she is laying a good pattern. You could be seeing open cells in the capped brood pattern because of hygenic behavior, a minor bit of disease, odd honey or pollen cells - any number of things. You are probably worrying about it too much. If you want to order a queen by all means do - but you might just use her to make a split.Yes the open brood are laid solid.
