Coinchina Survives?

Coinchina might be considered a "Lost country," as it was created by France out of the southern third of Vietnam.

Assuming that the French-Indochina War ended differently, what are the consequences of Coinchina becoming the Western-allied portion of Vietnam during an alternate Vietnam War?
 
wasn't South Vietnam pretty much Cochinchina plus whatever the loyalists had when the ceasefire was called anyway?

so probably a Vietnamese invasion.
