I agree that that's a bit much to ask for shuffling weight. Well, then, a little common sense should be used. Fine, keep half-pound breaks for the very upper classes, then go to .75lb breaks a little further down, and then to full pound breaks. I have to move ridiculous amounts of weight to move classes in FWD, and sticks n' autos are combined. Y'all can do it, too, within reason. If classes have indexes that are the same or within .05, then they can be combined. I made a spreadsheet before that showed how you could readily combine a *significant* number of classes. Less classes = more heads-up runs or "class racing".
I find it odd/comical/sad that I'm the *bracket racer* here, and so many of the hard core "class racers" run screaming to protect their own interests when you actually try to do something to bring the class racing back to class racing. Too many of them like to just pretend they are performance-based racers. Pretty darn rare for me to do a 1000' dump in a bracket race!
