AM i allowed to give some changes...
point one... dont stay on the back of shoesar lake... SALLA AIK MACHAR ADMI KO.... aur wahan lakhun nikal atey hain.... instead the further downvalley towards chillam are much more exclusive, if camping is a must stay in these valleys.. marmots are common,, bear seldom seen, for that you have to travel on your own made paths, ask any wild life employee over there... while stay at bara pani...
point number 2,,, rama meadows and lake are beautifull but rupal is something exotic... must visit rama but if possible pass your night at the dreamy village of tarishing, on the mouth of rupal valley
point number 3, if you can give one extra day to fairy meadows. than do it, and on that added day, climb a rounded shaped peak .. forgetting its name parabush or somthing like that, (ask any guide abt it on fairy meadows.) pass your night on that peak, heavanly smells of busshes up there and to see nangaperbet you are not suppossed to see up side but you will see straight onto nangaperbet sitting at its shoulder height.. that place is amazing...
point 4.. if you can give one another day to fairy meadows, than cross the nangaperbet glacier, and on other side there are a few huts, camp besides them and have amazing unique and unspoiled views... un common views of region... of nangaperbet.
Nalter is amazing... must to see the upper lakes of naltar,,, i think you should camp at fist lake and next day visit other two,, there are numerous waterfalls on the opposite side of mountains.. i along with my friends starts counting the waterfalls in that stony peak and they were more than 13...
over all, it is completely doable...
if you dont want to add any day than atleast follow point number one.
