LHB would be worse, coach length restricts the number of coaches to 22, and the need for EOG (don't expect HOG so soon, only handful of trains have it in India) means that total useful coaches would go down to 20. For an already popular train that would mean only increased troubles and unnecessary overcrowding in UR compartment (reserved compartment are rarely sacrificed in LHB conversion)
Deen Dayalu is a far better option, making life slightly easier for those who suffer the worst.
