Seems very unlikely, the cable pull will be all wrong for that rear dérailleur. It's not even Synchro on the down tube levers is it? There's potentially a problem with dropping 9s chain in between chainrings spaced for 6s chain too. If you're going to modernise it, you'll end up buying almost a whole groupset.
