No, --engine is not intended for this purpose:
* It is not available everywhere, especially, $(engine) needs
  to be introduced in TEXMFSCRIPTS.
  TeX Live 2007 defines it as follows:
    TEXMFSCRIPTS = $TEXMF/scripts/{$engine,$progname,}//
  Thus it controls the directory level below TDS:scripts.
  I am looking for the opposite, something like
    $TEXMF/scripts//$engine
* The number of subdirs isn't limited in Lua's module system.
  For very small projects, there is probably no need, but
  who wants to get limited in his programming efforts? ;-)
  Maintenance issues are important not only for large projects.
  Also someone might want to use third party stuff without
  control of the module names.

I read this as unlikely to happen.

Another solution could be to use a modified output of --show-path,
I will have to investigate.
