Sorry I was a bit late.. I was in Russia for the last month visiting relatives so I was a BIT off the "net" so to speak. ;-) If I don't qualify - that is okay... just some ideas to consider then:

I liked Heidi's logo, griffon with beer and sword in hand but not the "wraparound" look.

As for the shirt idea - what do you think about the "bowling shirt" (aka camp shirt - button down with collar), not the tuck-in sort of dress shirt but it will certainly be more "dressy" looking than a T-Shirt.

Black Shirt (everything will stand out sharply) - with red, gold, or silver secondary colors.

Right sleeve (worn like a patch)
The KGB crest: Place the griffon in a "kite" shield instead of a roundel - with KGB below (or above) the logo (still within the shield).

Back:
A nice large griffon logo (Heidi's logo with beer) - with "The Knights of Glory and Beer" above (in shoulder area)

Front:
Could have embroidery (for those who choose) - KGB name and title over the breast pocket.

Looks like these are good places to get an idea of the styles available (and what other designs look like)

I don't have the raw art to prototype this - but if Heidi can help - or someone send me the artwork to do it with I would be happy to put a "sample" together.

Just my thoughts.. but I like the RED or GOLD offset from black:
