Reconvening ES-10 to recommend a global travel ban on Israeli passport holders is procedurally and politically feasible. The UNGA has the authority to make such a recommendation under Resolution 377, and the majority of member states would likely support it, building on the precedent set by the 28 countries that already refuse entry to Israeli nationals.
118-148 / 61-77% of UN member states would probably comply, banning Israeli citizens from entering their country. Israelis would face severe travel restrictions, limiting their access to much of the world.
