That would be nice, perhaps we can already start some kind of vote to make a selection which theme's would be favoured as they probably all need a bit of customization then and I do not think you would want to make every theme available, or would you?
There are literally hundreds of themes available. Because each theme needs to be maintained separately due to the buttons, there will most likely be no more than 3 or 4 available. Each user will then be able to choose the one they want so there won't be any need to vote.
HINT: The current theme was chosen in an attempt to match the colors on the server manager. While the colors are similar, the use of the colors is very different and didn't produce what was really wanted.
This theme
http://custom.simplemachines.org/themes/index.php?lemma=131 looks much better on the eyes and with a bit of color tweaking, may look similar to the server manager in color and appearance. Anyone out there good at themes could take any theme, modify the colors to emulate the server manager and then present it. If acceptable, Shad can then update the buttons and include it in the choices. I am working on the above theme myself.
Remember however, there can only be 3 or 4 themes maintained so make 'em good
