Sorry I misunderstood ... You want finger wear on your maple fretboard ... that's easy!
I found the best thing is play in the sun on a hot day and sweat. Sweet Jesus, it's so damn hot. Do that a couple of weekends. Also not washing your hands before playing, and make sure you eat the greasiest stickiest things at the barbeque, and letting your strings get old and rusty. There you go. You'll have finger wear in no time guarantee!
