Kbin supports federating with both Lemmy (magazines) and Mastodon (microblogs), so just moving your account to Kbin and using their front end would be an option. I'm not sure if Lemmy plans to support pulling in Mastodon content long term
With Mastodon you can follow Lemmy communities causing posts and comments to show up in your feed. You can create a Mastodon List with Lemmy communities for a filtered view.
