I´ve seen a lot of it before but certainly not all, so thanks for the link.
Past years I´ve been busy a bit myself with customising Inca / Maya / Aztec / ... klickies. (there were many more Pre-Columbian civilisations in South/Latin-America, but those 3 are the best known.)
I´ve also been thinking of building a (large) Aztec, Maya or Inca pyramid with Steck or System-X.
Advantage of Steck is it has large "stone" stairways, whereas System-X only has smaller stairways. Advantage of System-X is it has large, flat "stone" roof-/floor-parts which can be joined together so you can put a small temple on top (f.e. like one of the Jungle Ruin ones) whereas Steck only has "wooden" flat roofs/floors. And I don´t want to go into cutting & glueing parts of buildings.
To use Steck I should probably dismantle several of my houses & castles and I prefer to keep those buildings together. Buying a whole lot of new Steck from DS-service for creating a large pyramid would be quite expensive. Maybe I´ll give it a try with a staple of 2nd-rate discoloured/yellowed Steck-parts, but I probably won´t have enough for a complete pyramid.
To build one with System-X, I don think I have enough parts (like walls from the 3112-Harbour Fortress) for a large pyramid, maybe a small / not very high one. I guess the stairways (usually on each side of such a pyramid) would have to be build by connecting a whole lot of small parts...
And meanwhile such a pyramid won´t be an original idea anymore since several other people are building exactly what I had in mind. Too many plans & ideas, too few hours in a day.

I might do a "try-out pyramid" when having time (and not being busy with other ideas) ...
