iTerm2 Replacement icons

I am a heavy iTerm2 user, for me it has replaced the Terminal app forever! One tiny bit that annoys me as a designer is the lack of good looking icons on the preferences window so I decided to create my own, unfortunately though I didn't check the application bundle until now realising the icons cannot be easily replaced, or better, the sizes seem to be hardcoded in the application and they look worse than the originals. In any case I have attached the PSD, feel free to download them and modify them however you like, I would love to see them implemented in iTerm2, if you know the developers feel free to send them this way or to my twitter page @fffabs :)

Update
If you'd just like the exported PNGs I have uploaded them here: http://cl.ly/BGIE
