Actually, I think a Hobbit Survivor could be about as long,
if, for example, various incidents in TH are featured
(the meeting at Bilbo's -does someone get poisoned?

-
Trolls, Rivendell, Goblins, warg meeting place, Eagles aerie,
Beorn, etc.).
Of course, for the dwarves it could end up being a
version of Agatha Christie's "Ten little Indians"/ "And then
there were none."
