Hey, I love what you're doing, I hate the practice jerseys on the game, and the fact that EA never run a pre-season or summer league mode on NBA Live drives me insane, so I always play games on the practice court and use practice jerseys when I do, cool huh! Anyway, PERSONALLY, what I would do if I knew how to do all this, most of the dark practice jerseys on the game are appropriate, they're similiar to what the actual practice jerseys look like, but the white ones are way off the mark, so in MY opinion they should look the same as far as printing on the jersey goes. I don't know how realistic you want these to be, that's entirely up to you, this is just a suggestion. Good Work...
Below are some examples of what I would do: (unfortunately, I could not get a picture of singlet version, but they look the same in black, grey & white)
