I used to visualize my bands after migration with an immersion of the gel in a solution with a high concentration of ethidium bromide for about 30 minutes. That works fine! In the running gel, probably would be fine but I think it depends also on the concentration of your sample. So, what is the result?

It should do... lots and lots of people do this around the world. Actually, all you need to do is add the EtBr to the +ve electrode end, it migrates in the opposite direction to DNA so will be drawn into the gel when running.
