Super tweeter for FullRange Driver


I have a pair of Audio Nirvana 15in Alinco Classics that I just got done getting into cabinets. After some listening impressions, I've realized I cant live with the high frequency response these things put out by themselves. They only go to about 15k hz. and it's made music lose its sparkle and sense of space and spacial cues. I was thinking of buying a pair of Fostek T90As and pointing them at the ceiling for a more even dispersion and better integration with the Audio Nirvana driver. My main question is what  capacitor volume would you suggest? Where in the frequency response would you crossover to the tweeter? Would wiring the 8ohm tweeter and the 8ohm Audio Nirvana in parallel make me need to change my amp(Audio Note Kit 1 300b Set) from 8ohm to 4ohms? Any other brands of tweeters recommended for a fullrange driver that is around 96bd efficent? Sorry for all the questions, incredibly new to trying to implement crossovers with full rangers. If this sounds like a bad idea. Please speak up.

Yes correct,
A high tech WBer 8 has highs to 12khz+, but its also nice to add the 12k-15khz sheen, glimmer, sparkles.
I don’t like super tweets, planar/nor ribbon tweets.
I plan to add a
DavidLouis clone of a famous Beryllium tweet, has a incredible neo dymium magnet motor.
Under $200,
Running a fantaistic 3.5 inch paper tweeter w a  2.2 Mundorf cap, Cuts off like 9khz,,,
so there is a overlap in fq's at 9k-12k, or what ever fq the DavidLOuis VX8 rolls off, I have no idea. 
I/m willing to fork out $200 to try the Be tweeter. and will post a note on its performance. 92db sens, same as the paper cone tweeter.
