Yes of course, parts wise it doesn't look too complicated.
If it fits the drivers.
Edit: Tried to cancel the order for Order the Dayton Audio XO2W-4.5K - SoundImports but it's already on the way.
Should I return it or would it be of use?

On the Q100 crossover, I can see a 3.9 uF capacitor. This would indicate that all you need to do to get the speaker working is to put a 3.9 uF film capacitor in series with the tweeter.
The Q100 specs state a crossover frequency of 2500 Hz.
Taking into acount the increase in impedance of the drivers at the crossover frequency, I would suggest you then add a 1.0 mH air core inductor in series with the bass/mid driver.
Monacor is cheaper than SoundImports for air coils. Check Monacor Europe (German Warehouse).

Wait, so I've checked the drivers now. See images.
I've only disassembled one speaker for now, and couldn't find any screws that would let me separate the driver.
Also, I'm not able to identify which of the pairs is the tweeter, can this be inferred by the resistance?
I've measured the resistance with a multimeter, across each pair.
The resistance of the multimeter terminals is 0.2 ohm.
The resistance of the driver wires is 3.3 ohm (at the label) and 3.1 ohm.
Can this be correct, or am I doing it wrong?
They go into a 4pin connector.

You're getting a resistance of around 3 ohm which indicates a nominal impedance of 4 ohm.
Don't try to separate the drivers!
The tweeter connection appears to be the one on the right of your third photo, if that little black wire going into the top of the unit is anything to go by.

Do you realise that this is a coaxial driver? The tweeter is in the centre of the mid/bass speaker, not separate from it.
I meant to separate the whole driver combination from the chassis so I could better check which is which, but if it's not necessary, then it's fine.
They don't have a common wire, it's 4 wires with 2 ground wires marked black. What I meant is I cannot see which of the pairs goes to the tweeter and which one goes to the woofer.
I found the screws, they glued a cover to the front.
Thanks for the hint, there are indeed markings. Let me send an update, one sec.

That seems correct.
On the third image:
Right side goes to HF+, AGND and has 3.3 ohm (minus 0.2 ohm of multimeter)
Left side goes to LMF+, AGND and has 3.1 ohm (minus 0.2 ohm of multimeter)
There is also another label reading Uni-Q 4 ohm
If necessary, I can separate the driver from the chassis
ok so if I get this right I need:
2x 3.9 uF film capacitor (which voltage?)
2x inductor is 0.68 mH (from here: SP-Spulen | Visaton)
Do I need to pay attention to specific types/or manufacturers?
And, I need to get some kind of terminal connectors for the new backpanel, I guess I can then just
solder the parts above to the pads of the terminals if everything is in line?
And, I guess I need to move the old blowhole/tube to the new panel then as well, at the same position.

Missed your edit!
Any film capacitor intended for loudspeaker crossover use will do - usually polypropylene types.
You can solder the parts directly to the terminal pads, but should fix them securely to the inside of your new back panel. The Visaton coils have a handy screw fixing and you could use hot glue for the capacitor and resistor.
And, yes, you need to relocate the port to the same position on your new back panel.
