Yes, do contact Kong. I hope they like the idea because I know my dog would love it. she is no longer hard on her toys but I remember not too long ago she went through toys like nobody's business. She,also, didn't like the indestructible toys. They just weren't fun like you said. I made a toy similar to what you described (see vibrating tennis ball) but not as good and it worked well as long as she was supervised. Your idea sounds great. I hope some company takes you up on your idea.
