There are dozens of precedents for a country splitting up to form two (or more) Football Associations, hence international teams.
However, there is NO precedent for two separate countries merging their two Associations to form one international football team, whilst remaioning politically independent of each other.
Moreover, "logic" suggest that any countries which tried it would not be permitted to do so by FIFA, since all the other Member Associations would be likely to protest that the merged entity was thereby gaining an unfair advantage.
Therefore, if you hope to see a single Irish international football team, then you'd better plan on living a very long time, for without an independent, united Irish state, it ain't gonna happen.
P.S. If, of course, the good people of the Republic were to see the error of their ways and rejoin the United Kingdom, then I have no doubt they might also rejoin the IFA ("Original and Best" (c) ), thereby getting another chance to 'live the dream'...
