So, would this work?

I'm only being half serious, I think. I probably would never do this (seems like a bit of work) but I was curious about whether or not it would even work.

So I have family living in the UK, my grandparents were born there, etc. And I cannot use an Ancestry visa, because I'm a U.S. citizen and obviously it's not a commonwealth nation.

BUT, let's just say I were to become the citizen of a commonwealth nation (And I know that in itself is a huge undertaking and I can't just "become" a citizen, I know). After I went through the years and paperwork and became one, then would I be able to use an ancestry visa?

Most commonwealth countries have similiar rules and regulations as far is immigration as does the UK, so I am not sure how you would be any better off and you would be picking up tax obligations along the way.  You are much better off trying to find a way to the UK directly if that is your desire.

Let's say you married a Canadian and went to live there and then eventually got Canadian citzenship.   Then yes you could apply for an ancestry visa assuming you meet all the other criteria.

Wikipedia has a list of all the Commonwealth nations, not sure about all their individual requirements, but Canada, Australia & New Zealand all have points based systems based on qualifications & work experience.

At least for me Canada, Australia and New Zealand all had similiar qualifications to the HSMP.  They all favour the < 30.  Some parts of Australia are easier then other, because they have regional programmes.  Canada might be a little bit easier then the others for a US person, but again, if you are going to "stragecially" marry a Canadian, you might as well "stragecially" marry a Brit.

It is easy for an American to become a Landed citizen in Canada, but you need a decent amount of personal resources to buy property and live in Canada for several years.
