I'm not real keen on removing blocks. The existing slots are in the 2-by
wood which sits on the sill plate.

Furthermore, I'm pretty sure most code requires a minimum distance between the
ground and the house structure if it isn't concrete. Providing a medium that
moisture can follow or that critters can burrow up into the house doesn't strike
me as the best idea.

Given the limited area involved, boxing in the underside of the joists and then
filling them with insulation might be a better alternative...
