As someone that lived through that conflict, I'd love to see this but you have no idea what you'd be getting into
Luft/spit whining would pale in comparison to the reaction you'd get from natives of both countries complaining about favoring one side or the other.
There's hardly an unbiased source of information about any of the conflicts between the two countries. Even wikipedia articles read like propaganda pieces.
The 1971 conflict would be interesting with the preemptive strikes by the PAF but more interesting would be the 1964 conflict which was fought on the west front and produced exciting events like the (disputed) 5 Hawker Hunter kills by a PAF pilot in under a minute:
Great reading even if it might partially be fictional

Alam had lost sight of the other Hunters, but with ample fuel he was prepared to fly some distance to catch up with them. Soon after crossing the Chenab River, his wingman Akhtar called out, “Contact, Hunters one o’clock.” They were flying at 100-200 feet and around 480 knots. As Alam closed into gunfire range, the Hunters did a half-hearted defensive turn which did nothing to spoil his aim; rather, it set them up in line astern for easy shooting in a row. Alam fired at the last Hunter against the glow of the rising sun and saw fuel spew out of the drop tanks, which had taken hits from the Sabre’s six guns. In a hurry to score fast, Alam shifted his aim ahead onto the next aircraft and fired another short burst. The Hunters seemed to fly across Alam’s gunsight like a gaggle of geese, and he obliged repeatedly, four times in all.
This conflict, like the later 1971 one, was very short lived with epic tank and air battles. I think the shortness of the conflict might actually make for a good sim scenario. Both sides were limited by resources but more so the smaller country of Pakistan and a proper campaign engine with resource mgmt would make this quite interesting.
Some air combat stats (again, disputed) about the 1971 conflict:

During the Indo-Pakistani War of 1965 the PAF was out-numbered 5:1 against the Indian Air Force and, initially, both sides claimed to have downed around 100 aircraft of the opposition during the 23 day war. The PAF fleet at the time consisted of 12 F-104 Starfighters, some 120 F-86 Sabres and around 20 B-57 Canberra bombers.[8] The Indian claim of 100 PAF aircraft downed was proven to be highly exaggerated when 86 F-86 Sabres, 10 F-104 Starfighters and 20 B-57 Canberra bombers were flown in a parade after the war.
The best reason, however, for a sim based on this conflict might be the opportunity to dogfight in the Himalayas! I don't think current technology would do that landscape justice though.
