This rumour has been around since a while, but lately its being revived. Actualy the holding is VRG who holds both brands Gol and Varig, the later one used more on international flights. If they do restart intercont my guess will be they will use Varig. I think the 787 is plausible as the company is sufficiently capitalized for this endeavour and further growth in the domestic market is limited by local infrastructure.
