Yes both restarting PV1 and compression should be achievable, but need to be managed carefully as the margins will be so thin. Lowest cost and highest effectiveness are critical, they will take their time to get it right.

Compression should allow the wells to produce for longer before they reach abandonment rate, and allow recovery of more of the gas currently in the fracture system. Whether that will add any significant tight gas recovery remains to be seen, as the reservoir is already very depleted. If tight gas isn't flowing now, dropping the BHP a few more psi might not do much.
