I've never seen people do it that way and ISTA doesn't outline that as the procedure to follow so I am unsure if that's the best way to do it - because I am now worried about the heater core and all those lines being subjected to the large vacuum induced by the vacuum bleeder. But If those components are ok with the vaccum then I don't see why not.
