So I conclude this discussion by saying that Minato wouldn't be able to the RDS because:

1)He wasn't sure whether it would be a success or not.

2)Due to the many risks concerning it.

3)He was unsure whether it would even work on Madara or Juubito.

4)He was too pre occupied in other things to even think about it.

5)Let's be honest, it would stupid on Kishimoto's part to make Minato do the RDS and either finish the series or make Minato terribly fail at using RDS and inflicting any damage on Madara or Obito.
