Yeah i do agree but sadjy, there is a reason some of us call it lemmyverse. We can see mastodon's content.
Since Lemmy doesn't really support hashtag, the core of mastodon discoverability, I think switching to a new software is better.
PieFed plan to support Mastodon this year. They already do it somewhat : you can follow PieFed user and a.gup.pe work well. You can also follow comment or post by setting up an alert.
Currently, only mbin can do that.
On masto that helped me finding new people or thematic discussion. It may not work very well but it does work with boost. From what i was able to achieve with it, it's an amazing tool 😊
