I have started building my "dream house" in stone and am halfway through the first floor when, for various reasons, I discover that the engineer miscalculated the loads for my slab.. in other words, the edge beam of the slab cannot support the weight of the house (two intermediate concrete floors and walls in lightweight concrete and concrete).
For part of the house, the slab is still not cast, so there I can redesign the foundation, but the other part is a lost cause...
I'm having some discussions with new engineers (unfortunately not easy to find someone who wants to take on this kind of mess..), one idea is to try to inject concrete under the edge beam in several places and reduce the point loads there, etc.
But now I'm considering building this part of the house in wood instead; the weight should only be a fraction with two timber floor structures compared to 180mm concrete, and timber walls instead of lightweight concrete.
I plan to insulate the wood frame with cellulose.
What am I missing here, what problems might arise?
Will I regret building half the house in wood and the other half in lightweight concrete?

A bit difficult to comment when one doesn't know what you're looking for. Personally, I would never consider casting two intermediate floors in concrete in a small house. That you use alternating wood and light concrete for walls, I can't see any problems with.
