My basic goal with the route I have gone is to protect the bottoms of my feed from overuse, and I concluded I needed as much cushion as I could get, rock plate-like protection from hard, rocky surfaces, and room for my wide feet. This approach does it for me. It might not be for you. The only way is to order a pair and see how they feel. One of the interesting features is that the flared outsole makes side-angle twisting pretty rare.
There is probably one factory in China that makes most of these. I have purchased various brands, they all seem the same.  Mine are 1.97mm thick. Size 10.43″ for my size 11 shoe. This link might take you there: https://www.amazon.com/Recovery-Orthotic-Reducing-Arthritis-Alternative/dp/B0BHW5BH2W? ref_=ast_sto_dp&th=1 The brand is Alfredex.  They all have sharp edges, so I apply Gorilla tape at the perimeter to prevent them from cutting the interior perimeter stitching of the shoe. If the insert is too short, it will cause lugs to start to separate. If that happens, they can be reglued. If the insert is too long, you will require too much force to place it in the shoe, so you may need to experiment. I am aware of the placement of the pads you described. I have used them and I had a bump similarly installed on a custom orthotic. All useless for me. Your results may be different. I have used carbon superfeet. Useless for me, they don’t do what I wanted to achieve.
You can read about my shoe here: https://runrepeat.com/uk/new-balance-fresh-foam-x-more-trail-v3 I pretty much agree with their opinions on this shoe. I own six pairs of these now, to guard against model changes. This should last two years. They actually work well in snow, with microspikes. The snow does not penetrate the mesh. The thick foam provides excellent insulation from the snow. When it gets really cold, I wear 40 below booties which are wide enough to fit over these shoes. Depending on the conditions, I then switch to Katoohla K10 Hiking Crampons or snowshoes.
I used to listen to the Doctors of Running Podcast. They get into the weeds on numerous topics. They are all Phd Physical Therapists who run. Very interesting. Listen to Podcast 214, which deals with even higher stack shoes that didn’t exist when I started wearing the New Balance Shoe. Be aware that the forces on your feet in this shoe for hiking are different than for running, which is their topic. As a hiker you will have lower joint loading forces, although some increase will occur on descents.
