I would not cut off the points. Can you add a narrow strip around the smaller ones (like a border)? The one star block in your picture borders up to a navy and looks fine. How is the size of the log cabin blocks? Can you change the outer strip and make that wider if needed? Good luck.
I once did did a sampler quilt and some of my blocks were not square. They were 1/4” smaller in height. I was able to put them all in the same row and it looked fine.
