Narrative:
Departed [on a trans-atlantic flight] with domestic segment being an ETOPS verification flight due to a right engine change. Just leveling at cruise got both R1 and R2 generator drive indications. Followed checklist guidance disconnecting both right engine generators. Contacted dispatch and [maintenance] with a decision made to return to [departure airport]. Dumped about 50;000 lbs of fuel. Upon landing immediate subtle pressure in a phone call from [operations] to extend and continue. Without extension they had 1+20 to find another airplane. One crew member would not extend. We left with five minutes to spare.
