I cut mine open this weekend. Total pita. Took forever to dig out the old sealant from the channels. Anyways, to the extent folks are replacing the Hella low beam projectors with EvoX-R 2.0, I took a few photos of how I modified the mounts to bring the projector lens closer to the frame. I used a dremel cutting wheel to remove the washers, then increased the fine threaded portion using a 4mm, 0.7 pitch die. I measured the ideal distance from where the lower nut rests on the plastic posts to where the washer supports the projector at 16mm. I used 4mm Hillman washers from Lowe’s to fit over the fine threaded portion, and I picked up some cotton gloves from Walgreens to minimize chance for fingerprints on the frame and reflector bowls.
Worked pretty well. I was able to fine tune the low beam and high beams using this method and it seems more stable than using separate screws and spacers. Still need to re-assemble the housings and put the new lenses on. My adjusters were literally crumbled in pieces so I’m glad a did this. Hoping the light output will be worth all the effort.

Nice job! The light output will be amazing, be sure to post pictures.
Edit: An issue I've encountered in the past with retrofits is that the cutoffs might not line up perfectly, as in the output from the two projectors will form an X shape instead of lining up perfectly. The easiest way to correct this is to bend the little tab that holds the cutoff shield in it's resting position up or down a bit to tweak the angle.

I used the 1.75" hole saw method described by Lesguy above. You cut one hole in each headlight assy to access one of the two adjusters. The other adjusters can be replaced without cutting. Worked fine. Very clean finish. I bought the plastic caps that snap in place. You must have a long (4 inches) T-10 torx screwdriver. Be careful not to cut too deep as you are close to the angel eye wiring.
Cutting holes for the adjusters only works if you're okay with using the factory projector assemblies. If you're going to take the time to do it you might as well have headlights that are actually good when you're done, at this point the projector bowl coating is usually cracking and flaking off from old age and heat cycling and output is degraded.

I was surprised at how far the interior bowls of my projectors had deteriorated. I got into this project largely to address the adjusters, but ending up cutting the lenses and updating the projectors since I drive at night frequently. So far no regrets except the quality of the aftermarket replacement lenses is not as nice as the OE Hellas. Not a cheap project but I rank it up with safety items like tires, brakes and steering. So it was worth it to me.
I agree, definitely a safety project. Retrofit lights are the only reason I was able to stop from 60mph in time to keep from hitting a deer smack in the middle of my lane. Pricey, but cheaper than a front-end repair job.
What lenses did you use? I used the DJAuto lenses with the chrome corners and had no complaints, as far as aftermarket parts go I thought they were pretty good. I don't trust them to resist yellowing very well though so I covered mine in Suntek PPF.

Including a source for polycarbonate lenses claimed to be OEM quality.
