I spoke (email) with Erno from Q tuner pickups who told me they are making an EMG 45 soapbar for 300/set for 6 strings. That sounds like a great option- not sure about lead time or when they are hitting the market...
My brain is now considering
Aguilar- New ceramic design
EMG- as economic option
It looks the like the "final solution" will be well over $300
