I'd say go for the Legra one _tom_ has done, I like the look of it, and as Philly says, ensuring Bob gets visible credit is important - if people like what they see, they might put business his way. If you put the Charvel one on, you could lose the 'interesting-ness' of having a custom guitar.
I was in the same situation as you recently, toying with the idea of putting a Jackson decal on the Warmoth Soloist I'm building. In the end, decided to go with a Warmoth logo - give credit where it's due, I reckon. :)
