No problem at all.
I've also created a version that uses a single A2S generator in case it's of interest. There's any number of ways you could randomise the pattern but in this example I've created a row of alternating lights and solid blocks, a second row which is the same but reversing the order, and a final row of just solid blocks. These are then randomised on the Y axis.
I hope that helps, please let me know if you have any questions about the set-up.
