it wouldn't be so bad to try a custom menu theme in sdcaffine. it won't hurt the system. if it works, you could transfer it to the appropriate location, but only do so if using a coldboot hack. I once bricked transferring a theme, and the byte size was identical on my pc and on the system. not sure what happened, but tiramisu saved me. I was trying to determine if you could ftp a theme with tiramisu as several people had bricked. you can, but it's finicky obviously.
