It isn't illegal to have a copy if you have the original. It is however illegal if you don't have the original.
If you're worried about the discs becoming damaged it doesn't make much sense to risk the wii itself by putting a chip in. I think the best solution is to teach your children how to change the discs carefully, do it yourself or just buy the game if the disc eventually gets destroyed.

I do know that having "copies" without having the originals is illegal. And I know a lot of people who have bricked their Wiis trying to chip it.
But apart from that I don't know anything!!
