sed backreference question

Hello,

I would like to execute a command from within sed (in a Bourne shell
script), similar to the following (this is just an example of what I
want to do):

echo $LIST | head -30 | sed "s/$.*$~$.*$~$.*$/`ls \2`/"

This doesn't work because the backreference does not get expanded when
`ls \2` is executed. Is there any way to accomplish this?

Thanks!
