Just by glancing over the topo, why skip over WLB the first day and head straight to Wallace? It would seem logical to me after an initial grueling first day hiking out of the desert, you'd want an easier follow up day. Why not do this:
D1/Shepherd Pass to Anvil/Pass lake
D3/around to Wallace
D4/Head down basin, jump on JMT, X-country to LSA
D5/ Layover after longish day
D6/Long, but mostly downhill hike out
The only thing about adjusting this route, is that perhaps you are not maximizing time in the "geographic" area you want, but you still get a whole layover day!
Just some thoughts from a semi-noob quasi fisher-backpacker.
