I am working on package for windows that can do just that. Totally portable and extensible. Based on ConEmu. But I am looking for beta testers. if anybody is interested drop me an email.

Currently it looks like this. https://dl.dropboxusercontent.com/u/52646091/cmder.png

Should work for you if you are using anything. But works out of the box with cmd + msys-git + some other godness.

Also spit window support, aliases, fullscreen, history search. Sublime Text like shortcuts.
