i already like tackle, and it wouldn't do much, because starters and other early route Pokemon already know/get tackle, and early starters/route Pokemon tend to weigh way less than fully evolved forums.
it would be really horrible as having that move and a move like leer/growl etc....
tl;dl i wouldn't like it, as we got plenty of good moves (Grass Knot/Gyro Ball) to do weight based damage.
