Smart LEGO Duplo brick

A few months ago, I figured out that CR2032 (3V coin battery) is little enough to fit inside a LEGO Duplo brick. In the interim, with my daughter, we built a Duplo house and put a small spotlight inside to have a pleasant atmosphere while the Lego figures had dinner. Also, very quickly, this question came to my mind: Can I build a Duplo brick with a LED to have the ideal light for our homes?
