In that case, you could try replacing mingetty with a script, which
performs a `stty erase ^H' before invoking mingetty. However, mingetty
might override this (one of the functions of a getty is to put the
terminal driver into a `known good' state).

Hmm. getty_ps uses /etc/gettydefs, which allows you to set the
terminal driver parameters (although those which relate to
canonical-mode processing won't work, as it uses raw mode).
If there aren't any command-line option, the simplest solution is
probably to modify the source code. I'm guessing that it will be
setting the erase character explicitly; search for `tcsetattr' and/or
`VERASE'.
