Considering your case of long outage (3-5 seconds), I would not recommend any of the mentioned methods. You will introduce a risk of getting into a situation when an actual failure will not result in a timely failover.

Also, methods to overcome your issues may be related to the version in use. Did you seek an official guidance via a TAC case?
