Working with Image Styles

Thank you for contributing this module, I just started with Commerce and found it useful already.

Would it be possible with Commerce File to have a price field for each image style of a file (provided type is image) e.g. XL, M, S? The goal is to let users select their prefered resolution.

I don't know if this would be good design but I thought a nice feature would be to have the following setup on the product administration:

Or could we integrate this functionality with Licence? So that we have different licence types for selected image styles?

I took a look at the code. Wouldn't it be enough to return the image style URI instead of the file URI?

Thanks
Daniel
