Using gallery2 only as a photo upload facility

I am developing my own CMS in php. I am interested in using gallery2 for only: Uploading photos, making thumbnails and retrieving images. Because I dont need any of the extra features, I don't want to fully embed gallery2 in my CMS.

Being that gallery2 is open source, I imagine that this could easily be accomplished by finding the code for the 'Add Items' link and use it as an example to create my own interface to gallery2 using the API.

My question is, does this sound reasonable? Is there a better way to go about this? And, has anyone tried this and have an example to offer with code.
