The first two things to think about IMO are water and structural integrity.
If the water table is reliably below the depth you wish to excavate, and you're able to do the digging well away from the load bearing parts of the foundation, it seems pretty practical to me.
Shoring to keep the excavated area from collapsing would be needed, you don't want the material towards the foundation sliding towards the new hole..
