I've never actually seen the workings of the slider but, knowing how it feels every time I use mine, I'm just waiting for it to crap out. Actually, it's felt that way since new.
How about replacing it with a bone yard unit ?
If that's not an option, probably the easiest replacement is with a multi-contact rotary switch, like you said. I didn't look at the LR schematic but, in the "old days", it was just a multi-tap voltage divider that controlled motor speed - a switch, a hand full of resistors and you're done.
'Course, in the 21st century, speed is probably controlled with a bank of microprocessors....
