I agree that Flash will give most herald levels a good fight and beat the lower level ones as well. Which is also why I said that people saying that surfer beats Flash without Mjolnir are blinkered, because it is not going to happen. However, based on what we have seen from the Keeper, it can be argued that if Mjolnir were to work the same way as the quantum bands, surfer + Mjolnir > keeper, because Mjolnir is likely> quantum bands.
Flash could hypothetically do all that you mentioned, but I'm not sure if he would be able to upkeep the constructs mentally, and some of those feats, like the creation of JLA members were performed by the top GLs, whose level Flash is likely not able to attain.
