I wonder How much it would cost to commission Gil Hibben or Kit Rae to make some of your blades. Kit Rae does more fantasy style blades, but Gil Hibben does sturdier more useable blades and also has some fantasy style blades too.
Yes, it would still be a custom saber, for the blade shape and the handleguard are the same. A Zwiehander is a completely different sword, straight double sided blade, no hand guard, and over 7 feet tall. The other one, I could not tell you lol
