"Not to take away anything from putting on the Tahs jersey - it's a special thing for me and every time I get the chance to do that, I go out there and give the best I can.
"But if that concept comes to life and I get the opportunity to play in it, it's only fair. That's where I'm from."
Folau played five times for Queensland in rugby league's State of Origin showpiece, but had never played rugby until he joined the NSW Waratahs in 2013.
The 27-year-old reckons it's a good idea but wonders how a rugby version it would fit into an already jam-packed calendar, and whether all players would get behind it.
"We'll see what happens in terms of that," he said.
All five Australian Super Rugby franchises and the Rugby Union Players' Association have endorsed the concept.
The QRU has also reserved Ballymore Stadium to host the match but it's understood the NSWRU is also interested in staging it in Sydney.
Folau will join his Waratahs teammates for his first pre-season training session of the year on Monday.
