I built a USACG Strat style guitar that looks like a strat but it has my name on it. Why? Because it is not a Strat.
Regarding whether it is cool to put the Trainwreck logo on a Trainwreck inspired clone: It's not cool because it is not a Trainwreck. And that is my opinion. Your opinion (and others) of course may vary.
Not trying to stir the pot. I am new to the board, but as a DIY'er I like to take credit for my own work. So anything I make, like Fender and Marshall, however inspired, will have my own name on it.
I'm thinking "Keithrick Car-Ash" for my first amp. What do ya think?
Short for: Keith, Carley and Ashley (my two daughters)
