any big(er) electronic store should have power supplies that can handle that I'd assume, the store I used for my reed switches lists a 36A/13.5VDC (500W) power supply for example. Although you might be looking at quite an expense for something that can handle 64A (I'd say a grand easily).
In any case, do you really expect to engage ALL drawknobs at the exact same time? If you could do this in groups you'd lower quite a lot the peak amperage you'd need (say, engage all of the swell, then the hw, etc. etc.).
I think Martin could also easily code in HW2 something like (x,y,z are user configurable obv.) 'if this combination engages/disengages more than x amount of stops, send the state changes for y stops every z milliseconds' (you could do 10 stops at a time every 100 milliseconds, say, lowering your peak amperage to 5A rather than 64).
