Of course...great concept for a chip!
Looking at your mock up though, the text needs to be made a bit easier to read. The denom might look better if you had it outlined in a darker color to really make it stand out from the brick.
With you wanting to use a picture like this as the inlay, going the Chipco route might be a good idea. It would definitely give you a larger area to display the image.
It's a great start and I'm sure you will get a lot of good ideas from the other on here. Depending on how your mockups turn out, I would like ot get a sample set of these if you are okay with it. You can never have too much Cubs stuff
