You mean this game specifically or zk as a whole?

This game specifically. The game stalled for a while as each side didn't know how to approach the other. If their incomes had increased during this time (maybe passively maybe via MM?) then the eventual end might have been sooner and a bit more climactic.

With a VERY VERY big maybe, if you ask me. More income could also just result in more dead locusts - around t40 minutes or so, someone had already fed 84k in locusts (killed 20k with it)... I really don't think non-growing income was the problem, more that neither side knew what to do with the metal they had.
East had a good opening when their sea-player broke through. At 33min, east has enough planes to probe if there is some aa north-west, then go in, bomb the factories and kill all those bombers. 2 minutes later, they do actually scout, but for some reason a few pickets and a razor scare them off..
Anyway, I don't want to go on about anyone playing bad. But I hope those were enough examples to solidify my argument.

Conclusion:
I don't think changing the zk-economy this much, especially with something that was intentionally taken out of the game already and avoided since then would be a good idea. If you really want to have a more TA/BA like endgame, you could try to make overdrive less diminishing. Or superweapons cheaper. Or nerf defensive things like shields. I think there are enough screws to adjust in the game as it is.
