I would love my country to be represented although we do share Incan heritage with Peru, of course.
As for the Cholet it is not a Bolivian typical house by any means. It is not common at all in Bolivia in general, rather a modern adaptation of particular cultural architectural tendency in a very, very particular and really tiny part of the country; even the Adobe based buildings, which one can definitely find in a larger geographical area with very strong indigenous ties to the Aymara, Quechua and maybe Incan cultures could not be a representation of what Bolivia is nor of the fusion you are talking about. Bolivia is truly a rather unresolved fusion of at least four main indigenous groups and Spanish influence, of course. If you asked me what Bolivia's Emblematic Quarter or Unti would be, it would be really hard to define just because of the forced melting pot it truly is. But you got me thinking.
The Incan Empire, on the other hand, however much conquest oriented and expansionist they were, has a very clear line of buildings, edifices and units that are truly representative, despite the fact that it conquered and absorbed other smaller civilizations and their particularities regionally. Unit wise, the Chasqui is not only recognizable, but absolutely central to what its society was all about, but of course it's not a military unit, unlike the Warak'aq found in Civ VI or the Kuraka's, for example. As for an emblematic quarter, the Tambo (Tanpu) would be a fun one to have which served as structure built for administrative (accounting offices), even economic ones in a way (storages of supplies, etc.) and military purposes (lodging, sort of temporary posts, etc.).
Another that I would love to finally see represented is the Tiwanaku Empire whose main ruins are found in La Paz, Bolivia. Another supposedly expansionist/agricultural empire too (not sure if truly militaristic like the Inca) which covered a portion of northern Chile, a portion of western Bolivia and the southern tip of Peru.
The Kalasasaya Temple could be it's emblematic quarter
