MACHU PICCHU Circuits

I’m thinking about going to Peru in mid August. I have been monitoring flights for a few weeks and looking into Machu Picchu tickets today. I saw that circuit 2 is completely sold out. I love the panoramic views of 1B, but from my understanding, it doesn’t include going to the citadel. Would it be too much to pair one of the circuit 3 routes with 1B? Is there one you would recommend? Or would it be best to hold off another year and book circuit 2 far in advance? I was planning to do MP as a one or two day trip from Ollantaytambo.
