I'm unsure whether a drop-in replacement exists. I use Lawnchair. It doesn't have the newsfeed when swiping left, but if you're okay with changing your flow a bit it could be good (enough) for you. You could create something with widgets (or maybe plugins) that replicate what you currently have.
If you can turn off swipe left to Google news, get a RSS feed reader, put a full screen widget on page one and all your apps on page 2. Make page 2 your default for home.
