Your case is a simple one. The problem is not which sim software you will be using. The problem is where exactly
is this network to be put electrically in order not to mess things up.

Although I do recommend also measuring your midrange and including that in the model, if you choose not to do so, first measure the frequency response and impedance of the tweeter with the original tweeter filter (midrange and woofer disconnected) and import that into VituixCAD. Then measure the frequency response and impedance of the tweeter by itself. As you design/modify the tweeter filter, try to keep the group delay the same as the group delay of the original filter/tweeter at least +/- 1 octave of the crossover frequency, and preferably +/- 2 octaves of the crossover frequency. I'm not confident it will be possible to do so, but I would at least try.
I see that measurement is a predicted room response. I suggest working with actual measurements, and go from that.
The woofer roll-off is important as others have mentioned. If the manufacturer cut corners, and left a hump, or cone breakup in the woofer response, that could be an area to improve on. Sometimes it's difficult to know what you hear that is off. With good measurements. and experimentation, you can probably find a way to improve things. Changing the response can be easy, but knowing what you like is sometimes harder to determine. I look forward to seeing the measurements.
Du..uh! That should be "Having the midrange and its xover in the model is essential"
