Personal opinion:
Your subject matter of the background, while looks cool, is still a bit too dark, that being the case, some of your server text gets a little bit hard to read.

SourceBans 2 as of right now has no plans of dynamic theme/template editing (ala wordpress style I'm assuming is what you mean), but it's not outside the scope of possibilities as a third party plugin, also, since it is built on the yii framework, there are some theme-ing items for yii available out there, I wouldn't be surprised to see someone implement something beyond the basic theme-ing of SB2.
