1000 hours WITHOUT factoring bring them in line with FAA FTLs. They could also approve 30/7 and 100/month sans factoring and most would be happy.
Yes, I expect most would, as it's entirely reasonable.
Now, if the airline was to have an incident or accident in the USA, and the FAA took a close look at the factoring applied...they would
not be pleased.
Withdrawal of landing rights in the USA would be a distinct possibility.
