Yes, indeed.
This is precisely one of the possible uses of a "font mapping".

Another, more mundane, is a simple solution for the "--" and "---"
  *lack of ligature* problem:

    "---" could be mapped to ^^^^2014 (em dash)
    "--"  could be mapped to ^^^^2013 (en dash)

and similarly for other TeX-specific ligature sequences.
