In the U.S., we often call it making a friendly amendment:
- Here's a friendly amendment.
- May I offer a friendly amendment?
- I have a friendly amendment I'd like to suggest.
- I propose this friendly amendment.
- We were stuck until Dev made his friendly amendment.
That's not good for every situation, because it's somewhat formal, but it's the only expression I can think of that comes close to your meaning.
More informally, when we're proposing a simpler plan or easier approach, we often say something with the word just:
- Why don't we just spend the whole week there?
- Let's just let it melt.
- Maybe if we just ignore him he'll go away.
I hope that helps!
