Tang Band W3-1364SA with Peerless XT25SC90
Something like this.
So a smaller tweeter would reduce the distance thus making integration more likely to succeed?

It's an excercise in learning mid/tweeter crossovers.
I didn't realize your goal here was in learning through experiments - I thought you wanted a better speaker from what you have - sorry for pushing you in a different direction .... Well, knowing your goals my suggestion is that you might want to get several different kinds of tweeters and compare them - you'll learn way more that way if your goal is to try things and build up some experience of what doesn't work and what does and how they tradeoff against each other. A done, a ribbon and a waveguide would all be interesting and offer different perspectives. You could also try back-to-back tweeters to form a dipole etc.
That's a good idea, ti may be what I end up doing. But to be honest, I would like improve upon the speaker I have already built. I understand many may think the Alpair FR is top dog but I am sure there is room for improvement and experimentation!

Thanks for sharing! That definitely puts this driver back in to the running!
I took the 3.5H horn off and presto - very wide lateral dispersion! Vertical stays practically the same.
For minimal c-c distance and high xo, 3/4" neodyme tweeters that come without a flange/plate are the best. An example
Dayton Audio ND20FA-6 3/4" Soft Dome Neodymium Tweeter
My measurements of Fountek NeoCD3.5H outdoor in a narrow baffle with xo and indoor without the horn in a normal baffle (less distance) Both 5ms.
One of my most successful MLTL builds was for the "Crossing Over Jordan" project. I combined the JX92S with the Aurum Cantus G2si ribbon. See my results at:
Jordan with a Ribbon MLTL
The A-C ribbon has exceptionally wide horizontal frequency response and more than adequate vertical response to achieve excellent results.
