Not really, the budget shows on screen...and Eberron would need more. It is essentially 4 feature length movies, which means that Rings of Power still had a lower budget per hour than Dungeons & Dragons: Honor Among Thieves, which has a pretty modest budget for a big screen film. A TV show that looked like Honor Among Thieves could conceivsvly run $75 million per episode.What you need to look at is Andor. I think something of that level could do Eberron justice. It also depends on what king of Eberron story you want to tell.
However, $58 mill / episode for RoP! Is that correct? If so, that is a highly inefficient use of funds.
Andor is a Sci-Fi show, not a magic-punk wide magic Fantasy Setting. Totally different league in terms of what would be required, which is why Sci-Fi is more often attempted than Fantasy in film.
