This seems a little misguided, seeing as how the financial crisis had many actors including regulators, home loan originators, academics which attributed far too much strength to certain portfolio management methodologies and models. Certainly there were actors within banks who were also corrupting the financial system, but in no way were they alone in the destruction of wealth.
And the rating industry, and geopolitical actors, and the World Bank, and hedge funds, etc, etc. I absolutely agree. But I'm afraid this could get into perfect being the enemy of the good territory. Unfortunately no model is going to be complete - even including these primary actors you would need to eventually model entire populations to capture macro-scale effects of the markets at play.
I don't think they need to be so perfect, however. Teasing out this sort of information ('mapping it') is not going to be a panacea that can detect all fraud. But it will probably be a useful tool to human experts who can combine knowledge from a partial map with information from other sources and a generally mature understanding of the industry.
