I've heard that the headband cushion from the HD650 can be used on the HE60, but the headband cushion on the HE60 looks really small, compared to what I remember of the HD650...
I don't know whether it is possible to do a fair A/B between HE60 and O2. O2 are still in production, and attracts most of the attention from after-market vendors, and DIYers. BHSE, KGSS, along with a full production line of STAX amps are available to drive O2. In the meanwhile, the only amp that I know, to some degree, dedicated to HE60 is the Aristaeus, which is extremely difficult to find.
My point is, there is a rare chance that one can own both the BHSE+O2, and Aristaeus+HE60, for a significantly long period of time, to listen to them and do A/B comparison. I‘d be very interested if anyone has done this kind of work before.
