Its possible but very unlikely. Planning trips early in the season to parks with new attractions opening is always a risky move, especially when its not a B&M they are building.
As far as how long RMC takes to complete a full conversion?
Georgia Cyclone closed on July 30th, 2017 and opened as Twisted Cyclone on May 25th, 2018. (9 months)
Robin Hood closed on October 28th, 2018 and reopened as Untamed on July 1st, 2019. (8 months)
White Cyclone closed on Jan 28th, 2018 and reopened as Hakugei on March 28th, 2019. (1 year, 2 months)
Roar closed on August 16th, 2015 and reopened as The Joker on May 29th, 2016. (9 months)
Mean Streak closed Sept 16, 2016 and reopened as Steel Vengeance on May 5th, 2018. (1 year, 8 months)
Cyclone closed July 20, 2014 and reopened as Wicked Cyclone on May 24, 2015. (9 months)
Iron Gwazi, Storm Chaser and Twisted Timbers are bad examples since they all sat SBNO for a while before RMC actually started work. But it would seem the medium sized conversions comparable to Wild Cat seem to take about 8-9 months from close to reopening. If we go by that, then this would likely open closer to late-May. However, who the hell knows what they're going to do to this thing. I have a theory they're going to install a giant truss-style lift ala Gwazi/Zadra and go for that wtf/wow factor since WildCat basically sits right along Hersheypark Drive. The other thing to consider is what this coming winter is going to be like weather-wise.
