So I posted this in the rules questions part of the forums but realized that no one probably looks at them for 1st edition anymore, so James Jacobs is my last hope hail mary shot at an answer.
Can quicken metamagic be used with the errata for wild arcana/inspired spell mythic abilities to make it a swift action casting time.
Ask your GM. I didn't really answer rules questions much here even when 1st edition was the active edition, because me answering rules questions confused folks who thought that since I'm the creative director my answers are "official errata" and some folks got frustrated and complained that my answers made it look like Paizo "didn't have its house in order" and I got feedback from management and fellow employees to avoid answering rules questions here. Considering how some folks would "weaponize" my "in my campaign" answers and turn them into tools to use against their GMs' rulings or to fight back and be disruptive in org play games, that was good advice.
Sorry I can't help you, but your GM is really the best source for ANY rules question, regardless of game or edition.
All that said... if this were my game, I would not allow it. Especially since mythic rules already overburden the 1st edtion action economy with too many swift actions already. It makes the game too unsatisfying and needlessly complex to pile on so many swift actions when you can only ever do one per round.
