LED Panel Lights - Other Sizes ??

Hi Rob.. its me .. Brianna ...lol..  just wondering if you all had any thoughts on different LED panel light sizes..  

Something like  a Lego 3 x 3 Stud Panel or 4 x 4 ..     would be useful !!  i only ask as if say you had a Sticker you wanted to be back lit by a panel, but the existing MED & Large panels are too big to fit in small spaces, and the 1 x 6 is too thin ...  

Don't have to make anything on my account ..lol.. just if ya had any thoughts on more square smaller options..
