Can you provide screenshots of how this looks? Likely, this won't go in as-is, but there's a student project underway to make it a bit easier to provide custom things like this without having to, say, override the logo every time you upgrade.
Simplify UI customization: handle custom logo.png properly
Review Request #2129 — Created Feb. 17, 2011 and submitted
Minor configuration feature: Allow customization by only replacing logo.png I made the layout independent of the logo size. Without my change the header layout is broken whenever the logo has a size other than the original logo.png.
Pushed to master as 7788529. Thanks!
