Yes Kitbach method is a killer one for epic scenes! (if you can use the elements randomly easily)

Yes your Monolith is very cool! https://www.behance.net/gallery/53179645/Monolyth

Magica will be "boring" only if your modules are little symetrical but if you take a little one no symetric module
then rotate it /them at each copy/paste/move ...sure it's by hand but like this you keep the control! ;)

Or if you use another technics : I don't see any boring here! ;)
