If there isn't alts of other characters he'll be called Erdrick, even if there are he'll still be called Erdrick with the other ones having different names like the koopalings, but i dont think theyll be in since they technically don't have canon names
I also don't think they'll be in since they'd have to do all or do none or else it'd feel weird, and the DQV hero wouldn't fit since he is purposely different than all the other ones design/fighting wise, the DQVII hero is younger than all the other ones and doesn't have the same proportions, and the DQIX and DQX heroes are customizable (though i suppose they could use the ones on the boxart)
The DQV Hero is also called Madason by some people since at the beginning of the game Pankraz (his dad) says something like "How about naming him Madason?" to which the heros mom replies with the name the player entered
fun fact, if the name you entered is Madason then Pankraz suggests Erdrick instead
I feel the same way you do about wanting to check out DQ but with SMRPG instead, seeing how passionate Geno fans are (and just hearing how much people love the game in general) makes me wanna check it out!
What about Luminary fans

Dragon Quest is waayyyy too traditional for western markets, its gameplay has always stuck to the same turn-based formula unlike FF which changes it up a lot (not that sticking to the same formula is necessarily bad, its just that it doesn't appeal to the west as much)
Also yeah, bad marketing
Oh, and for everyone saying Merry Christmas,
