Is there a term that can cover those consensus bullets in my post that is more suitable than agile? I personally may be ignorant on that part.
I suggest you don't use the word Agile at all because everyone has different expectations of what it means and it detracts from good arguments about the right things to do. Agile should never be more important than doing the right thing.
And you can sell your ideas individually if they're worth doing. There's no need for an umbrella term. That will only tie the ideas together and create an all-or-nothing mentality.
