Well the advantage would be assumedly reducing the back office cost (as is the IAM mission statement essentially). That would be ideal for anyone really assuming it all works to the suitability of the respective business.

From what sponsor said it seems BOOM2 is more tailored to simple/templated strategy which isn't surprising and is expected (theres only so much you can program in). That would suit many firms who provide mostly scoped or simple advice as the banks do. Might not work as well for firms that personalise each SOA more to each client (isn't completely templated).

I wouldn't say smaller firms would benefit from IAM being embedded with the banks. Once the software is doing all the heavy lifting and less labour is required offshore (which I assume is still the end game), I would assume anyone could pay to use the software if desired IMO.
