Goku vs Shuhei Hisagi

I am well aware of the MASSIVE stat gap between these 2. Shuhei is just a character who might have a chance against Goku's brand of fighting.

R1: Shikai CFYOW Shuhei vs current manga Goku. Can Shuhei last long enough for Goku to tire himself out, or does Shuhei's immortality run out before Goku gasses out?

R2: Bankai Shuhei vs current manga Goku. His bankai equalizes the fighters and makes both immortal, can Shuhei make Goku give up before they draw due to both gassing out their shared energy?

Both are in character.
