How to express a group suggestion? "I would like for us all to ..."
Let's do X.
How about we do X?
I think it'd be a good idea to do X.
X is a good option, don't you think?
I hope one of those helps. It's hard for me to understand what sentiment exactly you're trying to express, but I understand why you'd want to be vague.
"I would like us all to X" is how I would write it. The "for" really isn't necessary.
