Most likely these Shatabdies may not attract enough paxs, and shall be running at 100/110kmph only. It would be better to have Jan-Shatabdies, which can give same timing and avg speed, and a respectable patronage shall be guaranteed.
There is no point in spending a lot of section capacity by giving high priority to a Shatabdis carrying only 200-400 paxs where as full length 24 coach trains carrying about 1500-1700 paxs shall be waiting to let them cross or overtake.
