So the Abraxas is my best bet?
Always two ways about it. I will assume metale is right about the outputs.
The Abraxas will fit better with the SCs output whise, but will have more difference in EQ. However (I think) deliver better split tones and those will work nicely in a HSS set.
The Emerald is brighter, therefore the normal HB mode will tonally fit in better with the SCs, but you might have more output difference. The splits would not be as good I guess, but that can be helped by adding a resistor in series with the coil you send to ground (green and white wire). That way you donīt completly turn off the other coil, just turn it down a lot. The results is a slighly fatter and more powerful split sound. Might help with the Emerald.
