That would rarely work.
It's always just an approximation, but the more difficult and complex the speaker, the further away the simulation can be.
For a simple DIY 2-way speaker with no frills, ok. With experience you can tune something like this by ear.
But loudspeakers that are produced in quantities and perhaps sold for years? Simply being responsible for the shipping costs for floorstanding speakers in the event of dozens of complaints could kill you.
I know you know about it, but for others just coming in and reading the thread:
The tweeter in Tekton M-Lore is a classic budget king, which I know many DIYers have used. However, it does not go well with
Eminence Alpha-8A. With a smaller bass driver, however, the possibility of putting together a nice budget two-way DIY speaker increases. For example with this bass driver:
Peerless SDS Line 830656 5.25" Woofer Spec sheet: Peerless 830656 PDF Coated paper cone Rubber surround Aluminum voice coil Soft roll spider The SDS compact subwoofer family offers low resonant frequency performance, ideally suited for compact sealed enclosures. This 5.25 inch 8 ohm member of...

Low sensitivity, you can't ask for everything for a driver that costs like a hamburger menu.
(there are many good woofers from different manufacturers in that size that don't cost that much money)
The tweeter in Tekton M-Lore is:
Peerless BC25TG15-04 1" Textile Dome Tweeter Pre-coated textile diaphragm for improved consistency Damped cavity in pole for lower resonance frequency and reduced distortion Ferrofluid cooled voice coil for improved power handling Optimized face plate for linear response 104mm diameter face...

Then of course suitable crossover but that is another question. Anyway the drivers are above, especially in relation to the price, have a potential in themselves.
Maybe even with the drivers above together with a good budget 10-15 inch bass driver in a three-way system, but that's a topic for another thread.
Edit:
As already pointed out in the thread, it is possible to create good two-way speakers with an 8 inch bass and a 1 inch tweeter but then the tweeter often has a waveguide. Here is an example of an active one:
This is a review and detailed measurements of the Genelec 8050B powered studio monitor (speaker). It was kindly purchased by a member used and drop shipped to me. It costs US $1895 each when new. I was horrified when I noticed the speaker was simply put in a plastic bag, dumped into a much...
