Plestor, whilst it's true that EG doesn't do bespoke anymore (not since Tony Gaziano left to found Gaziano & Girling, or G&G), they still do MTO shoes and you can specify a particular design and a particular width, for example. You will pay quite a lot for the privilege of doing so!
Even top drawer wont fit very many (read pretty much anyone) people who can't be fitted by Alden (ortho lasts) + AE (widths...). Realistically TD is only useful for design based ideas that you don't want to pay full bespoke prices for (still ~1600+) hence my confusion on why it was mentioned in this context. Fwiw you're much better off going through a re-seller (ex leather soul) for better turn around speeds for TD.
Romp, are you planing to offer a more versatile range of English fabrics than PJT?
