No, but I gather you're a skeptic!
Changing the physical dimensions of the player doesn't change the physics of the racquet! 
Do you sell tennis equipment for a living?
I'll send you a Energy Polarizer and some special crystals, if you stick them in the handle or every racquet player performance will increase exponentially with every practice session!
The best advice any sporting person can be given, in relation to sports that use bats, racquets, paddles, cues, sticks, whatever. When you find a good one never change it, make it last as long as possible because changing kit just adds another variable and the user is already variable enough!
