Its great that you are really worried about general public who waits @nmj.
But for this reason they should not skip major stations getting benefits out of it. If you are really concerned about people waits at NMJ lc, request for a new line diverge from mq-nmj line well before nmj station limit and joins near tvr-nmj line towards tj. So this problem would be fixed and no need of fly over bridge and diversion if mannai.
