Does anyone have an idea for a JSO logo?

I have been putting a simple JSO made out of fuel tanks on my rocket for a while, but I want to try a new logo. I do not have many ideas, though. I would love some new logo ideas.

criteria:

• must be buildable on the side of a rocket out of fuel tanks
• I would like to try to keep the same color scheme (it can still have some other colors, though)
• I do not want some crazy complex and amazing design, I just want a simple logo for my rockets.

you can see an example of my current logo here.

(The logo is just on the capsule and the side of the rocket)
