I've emailed Gabe Newell. Not sure how suitable this is, but this is what I sent, in case people are still after a sort of template. I kept it pretty simple.

Hello,
I am adding myself to the count of people hoping you will take notice of our plea.
Please consider picking up the City of Heroes franchise from NCSoft.
This is not a one-sided grab for salvation - our community is large, close-knit and loyal. We are willing to donate a kickstarter and/or pay sub fees for this game.
We urge you, please, consider this.
Hopefully and faithfully,
