its been a while since ive gotten truely stuck with houdini. however, it seems that time has arrived that i must seek council from the more experienced users.
what i am trying to acomplish is a renaissance brickwork pattern

what i have managed to get so far is this:

this was done using two foreach SOPs. the first one to create a row of bricks all with random widths. Then another one to stack them on top of each other with different heights.
Now what i cant find out how to do is give the stacked rows different widths than the original one.
I have attached the file in case i have not been clear.
thanks in advance for any help ^^ i am truly up a creek without a paddle here
