So what I learned is:
"I have a cool idea for a character. He's a tough old human who was a former thug for a local guild. He fights with a pair of shortswords, wears beaten leather armor, but otherwise looks like a normal laborer in any town and NOT an adventurer. He has a slight limp, but hearty against poisons. Here are his stats:
Garruk
Hill dwarf (refluffed human) fighter (refluffed enforcer), N, criminal
S 15, D 12, C 16, I 10, W 12, CH 8
AC 17 (chain, refluffed as leather armor, defense style)
HP 14, Spd 25
Skills: Athletics, Stealth, Perception, Deception, Thieves tools
Atk: greatsword (refluffed as two shortswords) +4, 2d6+2
The rules tell you the game mechanics. You can re-fluff a shortsword as a BFK or a jian or a seax, you can re-fluff a greatsword as a flamberge or a claymore or a no-dachi, but you're talking nonsense if you re-fluff one greatsword as two shortswords.
If you want to play an Alice-In-Wonderland type of surreal game go ahead, but this is not the same thing as playing an expert in unarmed combat who's never seen a monastery, or a paladin who *gasp* doesn't wear full plate!
