It was a seamless experience and coherent for someone who has not seen the Original.
One little idea: When Karga grants land to the Mandalorians and then they leave basically the next day, it feels a bit off as it is now. I guess there was a side quest or two in between in the original show. It is not that a sudden departure does not make sense here, but it felt weird. I think this scene could very much profit from having a reaction shot of Karga. Any shot that has him looking up with a worried, sad or contemplating face would work. Because this is a setback and therefore relevant story beat in his ongoing search for a guardian, which concludes in the season finale. It would give the audden departure an active purpose in a side plot instead of feeling off. If a fitting shot exists, I think that is well worth 2-4 seconds of runtime.

On another note:
Until the Filoniverse is completed, this will be the Finale to my personal Star Wars Watchlist. If you ignore everything after it, it makes for a nice implicit finale.
We see Luke building an Academy, with Ahsoka last seen there and no Thrawn subplot introduced, the implication is that they build the academy together, which beings Ahsokas and Lukes Story to a very nice end.
Bo Katan has redeemed herself and Mandalore is finally reunited.
With Grogu there is now once again a force-wielding Mandalorian, that can be a bridge to the newly founded Jedi Order.
The short appearance of zeb hints at the fact that the Rebels crew is still around and active. If you watch g00bs edit of Rebels, which has the Epilogue as a separate Episode, you can just remove that Epilogue from your watchlist, not opening up the search for Ezra plotline, which makes the little hint with Zeb here totally enough.
Tatooine, known for its dangers and corruption, is under better rule and Boba Fett has found peace and his place jn the world. (we have seen him struggling a lot in the animated stuff)
And finally we have the first connections between Mandalore and the New Republic forming. Only between two specific people so far, but it is very likely to grow.
Oh, and Moff Gideon as the head of the Shadow Collective was defeated.
The only real loose thread left (when watching Rebels without the Epilogue and your Edits of the Filoni shows) is the Shadow Collective. But its leader gone and all points above taken into consideration, I am quite fine to just assume the will be defeated.
Do not get me wrong, I am very much looking forward to your future Edits. I sincerely hope the Thrawn saga plays out in a way that fan Edits can remove all build up to the Sequel Trilogy, which is unsalvagable in my opinion. Ending in a place where the Ezra Plot gets full closure and Thrawn is the final enemy would be perfect.
