These new numbers that I was toying with would require a +skill spell book. But it would be a +Meditation scrappers. Not sure what shard you are on, but I see one on Atlantic for extremely cheap. I'm seeing how putting it all together could take a bit of time and resources, though it is pretty interesting how it would all come together.
Short version of how it would stack up:
120 Disco
120 Music
120 Magery
~100 Meditation
100 Hiding
85 Stealth
100 Tracking
30 Necro
50 Ninja
I know you said it isn't a true need, but could still fit 2/6 in there. 40 LMC, 100 LRC, 17 MR, and you should be able to easily 70 it across the board. Build would still use a Crystalline Ring, but the non-faction version and one fairly loaded skill bracelet.
The more I look at this, I'm thinking it could be fun to try..
