That’s certainly possible, and is similar to what has been in discussion for the F1 and tennis.
I just don’t see it happening with all the logistics and cost involved as well as the requirement for local players who are re-entering the community still needing to quarantine anyway, compared to just playing away early or in Qatar/UAE/Kuwait and working with authorities who will be more willing to facilitate it.
By September, you’ll also have places that we will be much more advanced in the vaccine rollout and returning to normality making logistics easier in those countries. National federations from these countries may also be unwilling to agree to putting their players back in bubbles.
It’s all a lot of what if’s and maybe’s granted which is why I just think they’ll take the easy option.
Probably also depends on the draw as well. We’d possibly be happy to give up a home game against the pot 5 and 6 teams but keep it for pots 1 and 3
