Second, we're considering raising the house onto a higher foundation.
It's very low to the ground, and doesn't have sufficient piers. The
building code would consider that as "moved" and we'd need for the
structure to meet current codes. That's fine for the wiring/plumbing,
as I was planning to do that anyway. But I'm concerned that the wall
structure as I've described it -- just studs and siding -- will
certainly be an issue. There's no insulation, and I doubt the roof is
properly "tied down" etc..

What any of us think does not matter. You local building inspector is the
one to ask about codes. The house has been standing for 96 years so it is
sturdy. You can seal with spray insulation. Considering the age of the
house, you may want to talk to a local person that does restorations for
some guidance. It can be well worth the money to have something done
properly and not cause damage.
