Unscrewing the drywall may not work because it's often gluedThe hole thing will work, then repair the holesRarely can you remove drywall without destroying it.
If you shop around a sheet of 1/2 drywall can come as little as $3.50You should just buy new drywall Blow in insulation is the cheapest typically you can buy, but it has equipment rental costs as wellFiberglass batt is the next price upMost people don't install it perfectlyThe simpler the framing is, the better it will go inIf you have a lot of obstacles good luck on fiberglass batt.
Try having 1 or 2 people hold the drywall and safely remove the screws to take it downYou said you didn't want blown insulation, so maybe opt for Pre-Cut insulation blocks, They insulate great tooIf you just cant get to the screws, or for some other reason unscrew them, you might have to resort to cutting out sections of drywallCutting might take time and money, but it'd be worth it in the long run on your heating bill.
