Possibly, however everything that Barry can think of, Savitar will know.
So if Barry decides to not make Time Revenants, Savitar will know.
Also Barry has seen the Speed Force Bazooka so now Savitar should know that it is ready a few years earlier then it was.
Team Flash needs to strategize without Barry then when the fight comes to clue him in one piece at a time.
Totally agree with your last statement. I thought about that last episode . . .However, I took it one step further. How about Barry just sit out the Savitar fight entirely? That way Wally, Jesse and team Flash will have an even fight against Savitar.
