Combining ImageCropper with MediaPicker in Umbraco 7

As requested in this thread on our.umbraco, i want to create a new property editor, that allows for the content editor to select an image both from their local hard-drive and the media archive, to then be cropped right in the content section. Basically combining two already existing property editors.

This image gives a general idea about what i want to achieve:

Right now it is possible to use the image cropper on the images in the media section, but it would be more user friendly to have this functionality in the content section.

I am quite new to Umbraco and creating custom property editors, but I would like to know if this is possible.
