This could be done at  post-processing  time,
by putting a regular-expression find/replace
into the  &post_post_process  subroutine.

If a subroutine with this name exists, 
 e.g. you can define it in the  .latex2html-init  file
then it will be called, at a point *after* all the
internal tagging has been resolved into correct HTML.

Something like the following should be enough:

sub post_post_process {
  s/(HREF=")$CURRENT_FILE(\#)/$1$2/igs;
}


Please try this and report any difficulties.
If anyone else can see any not-so-obvious problems,
then please respond to this email list also.


Hope this helps,
