I like the leather bags, too, and mine were deformed beyond belief when I bought the bike.
The Leather lid inserts I tried.
Ordered and they wouldn't do what was promised.
So I sold them again. Unused.
Instead I reinforced the side with an inner plate, made from black 3mm polycarbonate and the lid with a pre formed strip made from 3mm PE glued and riveted (black rivets) onto it.
Before I softened the leather with water and saddle soap, stuffed the bag with styro pieces back to the original form and dried carefully with a hot air gun.
That's how they came out rebuilt:

Best if both worlds, imho.

Good luck,
