Animating or exporting variations

Hi all, I'm laying out a deck and railing system and was looking to leverage grasshopper to rapidly layout configurations (railing and post sizing options) - to show to a client. I see how to animate individual sliders to export images, which is useful. I am looking for a method to combine different variables before exporting.

I looked at Galapagos as an option but don't know what sort of fitness would I set up to scroll through different options, as there isn't a real logic (other than aesthetics). Is there away to just select variables and say "run" through all the options? Or is there an alternative option besides Galapagos?

I realize these are fairly open ended questions, but any guidance is appreciated. I've attached the definition here: deck%20railing.gh Thanks, Michael
