I would agree with this approximation: half Balkanites, half Slavs.
But Romanians are not necessarily further from Western Balkans than Moldovans, see this chart published in a PLOS One paper last year:
South Moldovans: Md-K, North Moldovans: Md-S, Romanians: Ro, Serbs: Se, Croats: Cr, Bosnians: Bo

How sampling is done still affects the results a lot.
