I don't think there's a problem having a story with multiple protagonists, a fellowship of heroes, and having a bunch of ego butting heads throughout the story could be very interesting.
There's also no problem whatsoever in having pizza, fish, steak and chinese for dinner. =)
Exactly the meal I had to snack on while watching Lord of The Rings.
I do think the best path forward imo would be to keep the origins as they are, just remain as recruitable companions rather than characters you can start as, and double down on a MSQ (Main story quest) for the custom character the player makes, where each companion they cross path with can have their own little story/interest in the world for a different take and PoV into the MSQ, but the MSQ being focused mainly on the custom character(s). That'd be more in line with older Bioware games (Think being the Greywarden having Morrigan and co at your side in DA:O).
That'd be the most cost-effective way of meeting a compromise of both worlds I think, where current work wouldn't need to be scrapped, and where the custom character can feel special and not insignificant compared to Origins (which is the main complaint that I'm able to boil most comments about it down to, where it feels bad / FOMO to be a custom character compared to Origin.)
It may help mending the individual desires/expectations of those that want one singular protagonist too, while allowing for a fellowship fantasy for those who prefers that. Which might be more in line with D&D, being a party of different protagonists. I can't think of a TT campaign of the top of my head where there's been only one player and a DM playing a campaign together.
