To be honest, I’d rather not see the mane six in G5, because more likely than not, they probably wouldn’t be the same characters anyway, and G4 was their story, I’d like G5 to be the story of a different set of characters. Though I would like to see something like how it was in G4, with older characters recycled a bit into sort-of-new ones, I’d like them to take some of the new ponies introduced in G4 and re-work them into somewhat different characters, I think that’d be fun, on that note I’d like to see a redesigned Kimono, though I don’t know how likely that would be.
Like you said though I’d like it very much if the Writers
didn’t change during the shows run the show might stay a bit more Uniform then, though I’m not sure how much it would benefit from it since most Hasbro shows don’t last more than three seasons so FiM was rather unique in that way, G5 then might not last as many seasons as FiM did.
All that being said, I am looking forward to what G5 might bring to the table, it could be quite fun.
