Should be fine.
Plain english you should substitute strength with dexterity in the rules. There is some support for this if we look closer.
If we compare Agile where it specifically calls out that you only ever add x1 dex, with finesse training which largely has the same wording as mythic finesse (it adds the 'if no strength then no dex' clause), which according to this FAQ does gain 1.5 strength, then I can't see a solid argument contrariwise.
