Anyone dremel the bottom of their shoe to get more toe-out angle for their SPD?

I have a weird stance. My left foot needs more toe-out than what the standard SPD allows. I'm using 20mm spacers and have knee pain cause I feel the need to angle my toes just a bit further (to the point where my heels will almost touch the crank). I'm about to take a dremel and try to widen the mounting space on the bottom of my carbon shoes. Has anyone ever done this?

Last year, I spend $350 on a bike fit on my gravel bike. I went to a highly reviewed bike fitter who said I have a weird stance and recommended the 20mm spacers and tried a lot of different positions. On long rides, I still get left knee pain. So I ended up buying dual sided pedals (one side flat), so when I only clip-in when climbing. But I just got some new shoes and want to always clip in, so as a desperate attempt, I'm thinking about widening the rails on my shoe.

Anything else I can try before I proceed with this micro surgery on some expensive shoes?

do it on cheap shoes first
Yep, pretty much every spd shoe i've owned.

Mount your cleats. Then clip the shoe in, if possible, mark out where the pedal is touching the shoe. Then slowly start the Dremel process. Take a little bit of material. The clip back in..... check out the interference, take a bit more if needed. Keep going until you have clear space and can clip in and out.

Just nibble a bit at a time. Don't take big chunks. Its easy to nibble more, but hard to put back material if you have nibbled too much!
I'd be curious to see a picture of the area your thinking about modifying, but if you only need 1-1.5mm of clearance for the cleat I think there's enough material in that area generally that you'll be OK. I wouldn't think it would take much to gain 2-3 degrees?
Thanks everyone. I'm glad to know I'm not the first person to try this. I'll take before and after photos when I try it tomorrow. I can't believe that after all these years, these darn things aren't more adjustable.

yeah I usually have to trim just a bit, I wouldn't worry about it. You have to be comfortable pedals.
To keep this thread updated, I found another solution than dremeling the shoe. I took the sole out and found what you see on the left side of the picture. The base (not sure what it's called) is much larger and has 4 mounting holes. The cleats mount to either the top or bottom two holes. In my bag of old cleat supplies, I found what you see in the right. Not sure where I got those, I think they came with some shoes I had purchased a long time ago and never used. I replaced the original with the one on the right side and this allowed the cleats to tow-in/out much more than with the original! Went on a long ride yesterday and today, tweaked it during the ride, and now it's perfect! I am a bit concerned that the support may not be enough, but it seems to have held up pretty well in my two test rides.

It's not adequate if your are using you cleats as designed.
