You might get away with sealing those gaps, but I would be sure that
you don't close something up that you can't monitor. I'd guess an old
roof with shiplap and asphalt shingles will probably breath well
enough that you won't have problems with condensation, especially if
your whole house is leaky. I live in an old house that has no roof
ventilation whatsoever, and no condensation forms in the attic--but
you will need to monitor this. Go up in the winter and look for signs
of condensation/frost.
However, using the bottom of the roof sheathing as a finished surface
does not seem practical. Isn't it going to cook up there in the
summer and freeze in the winter? To make it livable, I would think
you would need a ventilation space next to the sheathing, then
insulation and vapor barrier, and finally drywall or panelling or
something.
