Materials should be fine but I think it'll just end up looking like an unmaintained CM shoes... sloppy pair to be exact. Probably, if the toe was upturned, it can pass or you'll get boots with rugged rubber soles.
Nothing really to see in L'eclaireur in LA. Mostly furniture. The CCP they have are mostly in kangaroo leather. Other than that, it's just Isaac Sellam. You can check RO on La Brea or Backlash somewhere in Santa Monica Blvd.
If you go order directly from Rei, those can be modified to something better which is the good part. Although, I can imagine if he ever gets more buys from retailers, the bespoke/semibespoke aspect thing may disappear or may take longer or more expensive.
