Could you modify #62 by removing the four small dots inside the circle.
Could you also do another without the dots and making each of the four colored sections a different color? Right now, two are blue and two are orange. What would it look like with one blue, one orange, and the other two sections two other colors?
Also, the font for SIMC looks to us like it has been flattened a little. Can it be kept the same width but made a little taller. Then maybe write out the full name on the side like some of the other logos.
