Use a lift to get it out. I guess you could deice it, replace the drain pan and heaters, repair the drain line, repair the bent fan blades and possible some motors, replace whatever caused it to ice up in the first place and hope you don't find anything else wrong or bent. We could have a small coil like that replaced in 4 hours. I've replaced ones iced and damaged like that in the past. Everyone was happy at the end of the day.
