At this point it seems unlikely due to technical reasons. RPG Maker is a bit annoying in a way that these kinds of things should have been done in the very start and applying weaknesses retroactively is a pain. Applying them based on who is in a Warg and who is not is even bigger of a pain.
I'd only have made it something like 4 or 5% to get the 'weakness' indicator, and fire damage is rather rare in the game at the moment.

I thought of something that might or might not work.
What if a warg is treated as an equipped item like a weapon, accessory, or armor? I do know that some RPGs make some equipped items unable to be normally removed like cursed weapons or armors. If so, maybe a character’s warg can give stat bonuses and penalties and be treated as a "cursed" item that cannot be removed.
This could add the flexibility to allow the player to change wargs if you want to add that ability to the player later in the game.
However, if you cannot add equipment slots or lock them like cursed items in your version of RPG Maker, I understand if this idea will not work for now. Maybe this idea could be used if you port the game to a later RPG Maker version.
EDIT: I found some ways to add equipment types to VX Ace so that wargs could be an equipment type.
