Remember just because you suddenly turn to the dark side does not give you instant power. The dark side is channeled differently then the light. Mace might adapt well but Yoda might have a little more trouble. Personaly I just do not think it would work so well for them. I do have a better team then that though. The idea was brought up by vader in empire strikes back. The team of Vader and Luke. Imagine if instead of crying like a baby if Luke as had accepted Vader's offer, been and been trained by Vader. Well first off bye bye Palpatine. I do not think anyone could have stood up to them.

I doubt it. Sidious mainly relied on political manipulation. He is unmatched in that category. Yoda may have been more powerful in ROTS, but I think that changed in the 20 years of darkness.Vader was the muscle. I know Mace would make better muscle in a theoretical sense, as far as combat abilities (mainly agility) goes, but I think most of Vader's influence came from his image as the uber badass dressed-in-black-armor-officer-choking with the Imperial March playing in the backround 🙂. I'm not sure whether Mace would make the better Sith, but likely the more powerful one.
First off, Yoda is that skilled and wise because of the light side.
And Yoda was there at the rise of the darkside:
"By 200 BBY, Yoda, along with other great Jedi Masters of the age, discovered that the shape of the Force had begun to flux, becoming murky and uncertain. Studying the perplexing mystery in silent meditation, the Jedi High Council (of which Yoda was now a member) was unanimous—the power of the dark side was growing. "
He has battled through every temptation in the universe and not succumbed to the dark side. and your image of yoda looking silly as the dark lord only comes from what you have seen of him already.
