Hi, just wondering, are you also considering some quantum chemistry solver like coupled-cluster? It would certainly be good for a metallic system with a large number of baths. (I know it's no longer 'exact' diagonalisation)
For example, the moment coupled cluster from Booth group: https://github.com/BoothGroup/dyson/blob/master/examples/32-momgfccsd.py

It would be great to consider this. I'm afraid I'm not knowledgeable enough to know how well this would work without doing some research.

Hi, you may like to refer this article: https://doi.org/10.1103/PhysRevB.102.085155

Although they used configuration interaction, but that's similar to coupled cluster
