Normally, I would do it. But I don't think you should do any modifications to this board. Why? Because it would still look inaccurate and you could never sell it again as an official licensed product. This board is crap, but any modifications would turn it into unsaleable crap.
True but those that are willing to modify it, aren't the people that will want to resell it.
If someone wanted to resell it, they'd just get rid of it the moment it arrives like many others. They'll easily make their money back, especially with the mini hoverboard.
The people who want to modify however, are those that want to keep it despite it's flaws, but want to turn it into a fun project.
There were people in this thread that were genuinely excited about the prospects of being able to tweak things on it. I know that I'm genuinely excited about going and looking for some decent pink fur for the strap, and I have absolutely no intention of selling the board.
In short, while many were disappointed, it's still a nice thing to own alongside our more accurate hoverboard projects, and something that could be fun to tweak.
I think it would be nice to offer modified graphics since you're the main go-to-guy and some don't have access to the tools to do so themselves, though that's totally your call
Edit: I should also add that; as we all know, the general public are happy with Mattels inaccurate board. Thus I'm pretty sure if someone tweaked the board to be more accurate, with the credit of it being built off of Mattel's base, people would quite happily purchase it as a hoverboard replica, with it selling no differently than home-made ones.
