If you are looking for an ambient take on Miles then I would recommend the Bill Laswell remix of Miles tunes called Panthalassa however as you would expect it veers into dub at times.
In A Silent Way was as close as Miles got to total ambient music however the double CD of Get Up With It has the epic He Loved Him Madly at 32 minutes plus which is in this vein.
Miles post IASW period got both rockier then funkier and things like On The Corner sound very like a lot of Electronica today-not strictly ambient but a more upbeat relation.
Ascenseur pour L'echafaud which Albert mentioned is indeed still available on CD and is a very great Miles record, a bit bluesier than KOB but similarly melodic.
