Magic key upgrade question

[disneylover102]

I’m planning to buy a 5 day park hopper with lightning lane for December 15-19. I’m curious about the possibility of upgrading it to an Enchant key at the end of my trip (I know it’s possible they won’t be selling those). I have a couple questions about it:
1. 12/17-12/19 are blocked out for Enchant keys. Will I be still be able to upgrade to an Enchant key after visiting using my normal ticket (before upgrading) on those days that are blocked out?
2. Will the full price I paid for the ticket, which includes lightning lane, go towards the magic key or will they deduct how much I paid for lightning lane from the amount that goes towards the magic key?

You should be able to upgrade to the Enchant key even if it is blocked the day you upgrade. I suspect that they will deduct the value of the LLMP that you purchased from the pass and apply that to the MK.
