I think this will need some effort. A better alternative could be to use a
newer build-system maybe.

HMake testing is quite extensive but at the moment it is 8/10. I know of 2
bugs. These would be fixed using test test-driven approach i.e. first a
failing test-case would be added and then fixed. A production build-system
cannot afford any bugs. I am confident that I can deliver such a system in
the timeframe quoted and that the transition will be smooth sailing. Again,
the biggest advantage compared to the competition is drop-in header-units
support which could result in 2.5x speed-up. If this could be added in b2
for cheaper then well and good, otherwise you can consider mine.
