Aakash, I admire your enthusiasm! Only you will know when you get up on the trail how much extra energy and strength you have. But it is a mighty long day just to carry a full pack to Trail Camp. If you have the strength to haul it another 1300' (380 M) up and over Arc Pass, you are a lot stronger than 99% of Whitney hikers.
Going over Arc Pass on the route you laid out is definitely possible, but maybe not in the first day.
I've not seen people write about crossing Pinnacle Ridge, but it does seem feasible where you traced the line. Do understand, though, that the contours are 20 meters apart (65 ft) on the maps you are using, and so are not as closely spaced as the 40 foot contours on the maps used elsewhere in the Sierra. Crossing the ridge with a pack would be quite difficult.
Another issue: the dashed line on the North Fork Lone Pine Creek is NOT a trail. It is a use trail, and the dashed line is completely wrong as compared to the route hikers actually take. One has to know where to look for the route -- you won't find a trail there.
I have actually descended the drainage from N of Wotans' throne to Mirror Lake, and it is about as steep as talus can hang. It was quite an unpleasant descent, withOUT a pack.
Here are several suggestions if you are open for more:
Base Camp at Consultation Lake. Climb Whitney and descend. Next day, do a day hike over Arc Pass, and return via Discovery Pinnacle, back to your base camp. It would make a challenging day, but much easier that with an overnight pack. Doing the loop in the opposite direction would be easier: Climb the switchbacks to Discovery, take the easy descent to Crabtree Lake, then continue your loop, finishing over Arc Pass.
As another (easier) option, Climb Wotans Throne from your base camp.
Good luck! Let us know if you actually do anything like this. We would love to see a trip report.
