WI: Romania expels the Transylvanian Hungarians at the end of WWI?

The issue of Transylvania and the Hungarian population in the east was a burning issue since the end of the Crimean War in the 1850s and the formation of Romania as a nation. It served as a source of extreme tension from the end of WWI onwards, as Hungary wanted Transylvania returned, but the Hungarians within were enclosed by a majority of Romanians. It motivated the Second Vienna Award that stripped northern Transylvania away from Romania and returned it to Hungary.

But, what if the issue was a moot point?

What if the Romanians expelled the Transylvanian Hungarians at the end of WWI? The most obvious ramification is the weakening of Hungarian claims in Transylvania, due to there being less Hungarian Transylvanians there (if any) as opposed to OTL. Are there any major PODs that might lead to a harsher Romanian stance on the Hungarians in Transylvania, and them taking action to evict them?

NOTE: I AM NOT ADVOCATING FORCED POPULATION TRANSFERS AS A POLITICAL TOOL. This is simply a hypothetical conjecture.

Romania becomes a pariah state with no country but Czechoslovakia and maybe Yugoslavia remaining on friendly terms. Sometime in the next few decades the USSR, Hungary, and Bulgaria invade Romania and nobody lifts a finger to help the Romanians. All Romanians are expelled from Transylvania, Bessarabia, and Dobruja, with those territories being annexed and re-settled by Hungary, the USSR, and Bulgaria respectively.
 
This doesn't change much until post-world war 2 as Germany and Hungary can bully Romania as per otl into giving up northern Transylvania. Post World war 2 Romania won't have a Hungarian population.
 
We would have to be insane to do that since Romania signed the Minorities Treaty.For the expulsion to happenhapit would mean an ultranationalist government wich,I believe, would also push for another war between Romania and Hungary to achieve a new border at the Tisa.
