Is is possible to put a WML on a third generation Glock 23 without compromising reliability?

Yes. Best practice...

install 11-coil springs in standard capacity G23 magazines
don't over-tighten the light on the frame
use standard velocity 180gr rounds

Never had any problems in about 20k with a 23.3. Never upgraded mag springs.

Finger tight plus a quarter turn and done.

Understood. Best practice, not required practice.

And that info was Glock's advice to users that were experiencing .40/WML combination issues.

Absolutely it was.

Disciple, just be aware that some 40 cal Glocks that are reliable with weapon mounted lights develop into being unreliable with weapon mounted lights.

I have had good and bad experiences with multiple 40 cal Glocks and WMLs over the years. I don't want to go into it. But the information I mentioned above is something you should be aware of.

Any advice on using G22 and extended 22 round magazines in a G23?

Only the usual, verify function with chosen combination. If using a G22 magazine in a WML-equipped G23, I would put the 11 coil springs in the mags.

As ggammell notes, it may not be necessary.

The X300U-A is probably your best bet in regards to lights. I'd avoid the TLR series and X300U-B. I'd wager a large majority of the problems stem from mongoloids cranking them down too tight coupled with the characteristics of how .40 Cal glocks shoot.
