That is possible with our current system but only for total ranks of all skills or a subset per design. They would be featured as a separate design style as F2P and Skiller/Non-Combat signatures are
here. We would just need slimmed down designs, for those interested read
this topic.
As for optional display of combat and total level that's not doable right now on a per-user basis or even a nice way of showing one skill. There would need to be a more customizable system in place for this

.
Text-display on the mini-profile would be easy for those who are in our highscores system. The problem with that method is that there's already so much info there. The custom signature designs would be the preferred method (for me at least) as people on other websites could use them as well
