As far as I'm piecing your intention here together is that you want to replace the tiny 90's style icons for ships and images we can select with generated ones, and maybe add a few more icon types for commander faces and such. Maybe give the UI icons an overhaul.
Doesn't seem like a big change; do whatever.
Much more interesting would be an integrated image generator for ship/missile designs, an overhauled iconized UI or visualizations of space battle results, but that, much like the idea for that dynamic commander portrait generator, seem beyond your intent in this thread. Correct?
