#3. Can a makeshift team win the NXT Tag Team titles at WarGames?
An NXT event usually has a title change or two. WarGames has two WarGames matches, so those alone make up for the need for title swaps this year.
Imperium won the NXT Tag Team titles from MSK at Halloween Havoc, by capturing the titles, they could be setting the stage for WALTER to join NXT 2.0. If he doesn't, he should join the main roster.

The challengers are a makeshift team. Kyle O'Reilly represents the old guard of NXT while Von Wagner represents the new guard. WWE officials see a bright future for Wagner due to his size and athleticism.
Wagner needs help with the promo department. That could be why he was paired with O'Reilly. What muddled things up was when Wagner showed up at Adam Pearce's side on an episode of SmackDown before Survivor Series. It could have been as protection from Brock Lesnar.
If the big man is already earmarked for the main roster as part of a stable for Pearce, then the partnership with O'Reilly could be short-lived. The duo won an opportunity to win the belts at WarGames by defeating Legado Del Fantasma. If O'Reilly and Wagner are successful, then Kyle will have won the NXT Tag Team titles four times.
Wagner might turn heel after WarGames or he could move on to SmackDown. We haven't seen much emotion from the big man in NXT 2.0 and he would be better suited as a silent heel.
O'Reilly is still one of the top faces of the brand, but his future is uncertain. For those reasons and the fact that Imperium is an actual team, the challengers will walk out of WarGames with empty hands.
Prediction: Imperium retains their titles over O'Reilly and Wagner.
