    Ideally ls would accept a new --format=FMT option that would
    work like find's printf format string.  Then it'd be easy to
    add a new option to make ls use a format string with fixed
    widths to restore the old behavior.

Would you like to implement that?
If that's the solution you prefer, it will certainly work.
