IMO I can not see this working due to instabilities of the asteroid
perhaps the idea of tumbling the asteroid about its long axis in the
direction of its orbit could be pursued - this would give the
abilite to have multiple habitats along the axis with graduated
artificial gravitys - you can then redirect the light from the
surface into these habitats by the use of mirrors and light tubes.
it is an idea.
