Well, no, I don't (what kind of the device do I need?)
BUT I do have a swamping (shunt) resistor in // with the Crites 3636 autoformer that attenuates the midrange.
I used to have a 10ohms resistor there, then (as I was attenuating -5dB) a friend suggested I tried 12Ohms instead, which I did, but since then I switched to only -3dB of attenuation which would normally asks for a 16Ohms resistor.
I don't know if that resistor alone could be the cause of such a deviation...
On the other hand, I kinda thought that having a swamping resistor in // with the autoformer would have the network see a much flatter 8Ohms impedance throughout (?) (assuming I would have the correct value resistor which isn't the case here ^^)
So maybe I first try that, of course, I should first buy some 16Ohms resistors and see what happens...

Since you were able to measure the midrange response with REW, why don't you first measure the tweeter response before you start playing around with crossover components? You need to know the baseline performance.

Using a "universal" crossover with drivers it wasn't specifically designed for is very likely to give results that are different from the nominal ALK values.

  Yeah, I'm going tp measure everything of course but, what got me interested in the midrange to tweeter crossover behavior is that, when I measured the full bandwidth with the tweeter in the wrong polarity, the resulting gap was way too wide. There is clearly some overlap happening there.
  
  The overall response is good, and it sounds good too, but yeah there is clearly room for improvement.
