Collingwood admits he could be willing to take part in the landmark three-match series in Lahore providing security measures are in place.
The touring side will be coached by Andy Flower, forming part of the International Cricket Council's bid to step up the return of major matches to the volatile nation.
The World XI series will be followed by a short visit by Sri Lanka for a Twenty20 match in October, then a Twenty20 series against the West Indies a month later.
"I've been asked if I would be willing. But until you hear all the details of the security and everything you can't really commit to anything," he said.

"Andy asked me if I would entertain the idea, so that's the starting point.
"Certainly the thing that would interest me is if, at 41, I could play in a T20 international in front of that crowd, that would float anybody's boat.
"The tag of a world XI at 41, I'm quite proud of that if I was to get into that team."
Collingwood added: "What I do remember about Pakistan was the passion of the supporters.
"I think Karachi was probably one of the loudest crowds I have heard during an international match. They love cricket out there and it's a tough place to tour.
"If it was England and we weren't allowed to play cricket in England, we would be doing everything possible to get it back.
