All 460 and 480 bodies accept the A60 rings. All AKG 451 style capsules (CK1, CK2, CK3) fit into the reducing rings, allowing their use on the larger 460 bodies. CK4 are reported to not work with the rings and work only on the 451. A61 works with 460/480. A51 only works with 451/452, unless of course you couple it with the A60M rings. Then I believe you can use the CK1,2,3 caps with the A51 swivel to an A60 ring on a 460/480.
Don't forget the VR-61 and VR-62 extension tubes either (and their 451 line counterparts the VR-1 and VR2).
In addition to this, you can use EVERY capsule built by Blue in some way, shape or form. All of the screw on lollipop caps fit into the A60M ring. All of the bayonet style capsules can be used with a custom adapter built by a machine shop in the UK (sold on Ebay), along with the A60M ring.
In addition to this, you can also use Gefell M7, M8 and M9 capsules with this bayonet adapter and the ring.
