Use 50 dB scale to show how flat it is. I would work on getting those terrible breakups at 6 and 10 kHz much lower. 2nd or 3rd order. You get now breakups only ~10dB lower than highs from tweeter. That would not sound good to me.
Yeees, it is that easy 🙂
Build it, listen to it, compare it to well designed speakers, mod it, discard it, or any other option.
Good luck.

Also make sure to use a HPF that significantly damps the resonant peak of the HF driver in the measurements (acoustic and electrical impedance). I'm not sure what HF driver throat or diaphragm material you're using, but a first-order HPF with a corner frequency at 1kHz might expose some issues.
Then look at the off-axis responses, and make sure you're not causing any nastiness in the power response.

And do not forget to plot phase. Maintaining smooth phase around the crossover region is desirable. In general phase should be as smooth as possible without abrupt swings. Gently slope is ok.
No, it is not that easy.
Is driver D3 ordinary tweeter or some small fullrange (2" - 2.5")? If it is conventional tweeter, it will burn in seconds - the crossover frequency is too low and the slope is too slow at only 6 dB/octave. If D3 is fullrange, then it is OK... sort of.
Driver D2 has pronounced peaks at 6 and 10 kHz, you must use second order Low-pass filter (L+C). It will bring down region between 1 and 7 kHz, to level it flat with D2 output.

When you have it built, reverse the tweeter leads and mesure, look for a huge dip at the crossover point.
Then you'll know for sure.
