Look for advice about wavecor tweeter TW030WA08

At that price and free shipping if in the USA its a bargain.

Be aware of its sensitivity 88.5dB which needs careful consideration to which unit you are going to cross it over with, ideally you will want to simulate it with your chosen drivers to make sure it will work in the your design.

I just have a quick idea. What about the "Wavecor WF168WA02 6-1/2" Paper Cone Mid-Woofer 8 Ohm"? And crossover at 2500hz?

for lazy crossover: Dayton Audio XO2W-2.5K 2-Way Speaker Crossover 2,500 Hz
 
I don't know how much time you have left to hit the buy button on this?

Its a bit rushed, it looks like it is achievable, but it would be nice to have some more sensitivity on the tweeter to allow for some adjustment of levels and a good match.

The two drivers together would probably crossover easily below 2Khz, consequently the off the shelf solution 2.5KHz crossover would be less than perfect. it will obviously work but how well?

I am sorry to suggest that it might be more sensible to hold off buying for the time being, and explain what you want to achieve in some more detail.

The people here will help with known and proven combinations of drivers and crossovers. The drivers specs you are looking at are good, they probably deserve a better crossover than a stock solution and some more time working out a an optimum design.
