Aggregation- Is this idea possible?

I subdivided a pyramid into 3 different shapes - components (seen below as A, B, C) 

I formed my own logic 

A= A,C
B=A

C=B

I've been building it up as an aggregate using this logic, however, I want to make many different iterations (hundreds) either using this same logic or even using a different logic. 

However, I've realized making these take alot of time and I was wondering if there was a way for me to do this easier..? 

I followed this video for some grasshopper- but Im not sure hwo to change it to what I need: http://www.grasshopper3d.com/video/python-in-grasshopper-02-recursi...
