That's exactly the idea behind a slightly larger base turbo run at lower psi but the same CFM flow.

Also to answer another question:

Water injection is mainly for detonation control. It will not add much power. Now combined with allowing more timing then it should however there is a Very fine line and I also mentioned the idea of multiple programs.

The charge temp reduction is also partially offset by the volume the water mist/vapor takes up. It is not compressible nor ignitable and therefore takes up room for subsequent air/fuel mixture.
Yes it is minor and well worth the anti-detonation protection.
