When Issei gets his AxA form where he probably turns into a dragon(which i think he will awaken when he faces either Rias' team or Indra's team) he will definitely achieve power at the level of a Dragon God leaving Vali behind. What do you guys believe Vali will get to attain Dragon God level power to be equal to Issei? I believe Hades will approach him and show him Lilith thus Vali will fuse with Lilith to get that type of power. Hades was creating artificial Super Devils with Dragon God class power. Vali who is actually stronger and at the level of the Heavenly Dragons should be able to get to that power level. Meaning the final of the tournament which will probably be Issei vs Vali will be an apocalyptic battle.
