Well, part of making a dio is using what you have in creative ways.
This certainly isn't a bad idea, but there are some conspicuous problems -- what if they don't have the Hawk you're using? I think the biggest problem would be style. Unless the two of you took your photos with similar cameras in similar lighting and you used focus and accessories in similar ways, your dio would look a bit patchwork.
If a few people who liked to do things in similar ways got together to work on a dio in this manner, though, the results could be awesome!
