Tata-YPR frequency increase almost next to impossible if going by the same time. Other days slot occupied by Trains from HTE...also there is a SBP-YPR special on the same time slot. Maybe new train with a new time might be a possibility.
Instead of going for all this, if Tata-Allp can be made independent with better speed, it will surely be a good connectvity for people going to KPD, MAS...can help solve lots of issues ( as it runs daily).
