I can walk you through the process of managing a HiC2 pool -- high CYA & high chlorine. It shouldn't cost any more (and may cost less) than running in the ordinary way.

There is very little I can do in the way of a quick fix:
+ you can not safely drain and refill your pool, without hiring a professional to set up suction to hold the liner in place while the pool is drained.
+ even then, you can not drain your pool now, because the ground is wet.
+ you can do a 'drain in place' but you'll need a winter cover that is 15 - 20 feet wider AND longer than your pool. It will probably take a week, and when your done, the water temp will be whatever your fill water's temp currently is -- probably colder than it is now.
+ without knowing your fill water's condition, I have no idea what your TA and CH would be at that point, but currently those levels are too high for a heater.
+ there is a way to 'warm' the pool a little (3 - 4 degrees) assuming your current liner is light colored, by laying a large piece of black plastic on the bottom.

There is an option you could consider. Solar covers aren't that expensive -- certainly less than the cost of 2 weeks gas heat on a cold pool. If you're willing to sacrifice the cover, you could lower the pH some, keep the chlorine high, and begin aerating. Doing this would allow you to strip BOTH excess TA and the volatile oxidation products that are forming. It might damage your cover -- or it might not.

You'd need to order this fitting (after verifying that you can fit it into an existing return socket):

Using this fitting would allow to rapidly and effectively aerate your pool, even with the cover in place.
