Hello Greg and Welcome to the Forum:
The house can be jacked up just enough to release the present foundation, block it there with wood cribbing, take the remains of the old foundation out, dig a 16" wide trench under the preimeter down to hardpan, pour a new concrete footer at least a foot thick, lay 8" concrete blocks up to the house and remove the cribbing letting the house down on the new foundation.
Quite a project there, I wish you well.
