No - there isn't.Is there any possibility to ask IRCC and get their response before accepting the offer both for sponsoring and RO issue?
It's entirely up to you if you take the risk or not. Again, based on the cases we've seen here, your employment will not be accepted by IRCC as meeting the requirements for the exception. This will be counted as time outside of Canada.
Note that to sponsor your child for PR, you must be physically living in Canada since you yourself are a PR. There are no exceptions to that rule. You won't be able to sponsor from outside of Canada.
