Would Mayweather be considered a much more powerful puncher

[Shambrolic]

if he knocks out Maidana?

[Juof]

He bets on himself to win a UD so makes extra mills everyone knows he has one punch ko power

It took 2 sucker punches to KO Ortiz

Yes, many fans would think more of his power if he stopped Maidana who has never been stopped. He has always been a decent puncher but not a big puncher. A fighter's power is not going to increase in his late thirties. I think it's possible he KOs Maidana but more likely he doesn't.

[Jack Napier]

no
stoppages come in different forms
if he outright KO's him, it's on Maidana walking into a nasty counter
that or Floyd digs in hard body punches
most likely a stoppage here occurs via fatigue/mental checkout
Floyd will break him down, sap his confidence, and end him late
that wouldn't add quality points to Floyd's power gauge

No. He has always had enough power to stop most of his opponents, even at welterweight, but he needs accumulation. It's doubtful that he'll ever open up enough to get a stoppage nowadays, no matter the opponent.

[GrandpaBernard]

I don't think anyone will ever consider him a powerful puncher

Maidana is far from iron and easy to hit
