It's not possible now as ER will not go for procuring LHB Rakes for a Bi-Weekly Train that may give good patronage but is not so popular as Poorva Express or Purushottam Express... it's rake also does rake sharing with some other trains like Kolkata - Agra Cantt Express so their LHB Status will also come into consideration... this train may not become LHB for the next 10-15 Years... at most a new ICF Rake that too when it's frquency will be at least 4 Days a Week :-p
