I tried building that once, but it makes the package grow a lot and the nsis tool we use to build the installer couldn't handle it (it seems to have a limit of 2GB input size).

I think @compnerd has plans to help reduce the toolchain size by having shared code in dlls. That's probably a long-term project though.
