No much. It depends on if all of them are too small. Let say it is a standard 8' drop, that would be about 14 steps. if you made each step a half inch wider you would lose 7' of clearance at the bottom. If you have the head room you could put a landing in about 4 steps up and then have two smaller sets of steps at the bottom on each side. but your look a about $400 to $1000 and a good bit of work.
