Flint, Forge, Foundry?
When it comes to how the aspect of Creation, Transformation and Destruction has incarnated into the world through the ages, we've seen how the Primary Incumbent Hour has been usurped by the Rising New Hour. Meant to represent how old technology is discarded when newer technology is invented/discovered.
If that's the case, should we expect a new Hour (Perhaps even a God-From-Steel) to replace The Forge of Days as the head hour regarding Creation, Transformation, and Destruction?
Keeping with the theme of it still being an F named aspect, I think Foundry makes the most sense with the removal of single specialist smiths doing individual work, and now broadening to encompass the whole system/facility that embodies how things can be created, transformed, and from these creations of war; destruction.
Also we can redeem the aspect of Sky from the depths of Flint 's shattered remains as now our Foundry's churn out steel aviforms that are unlike any beast before, who can sail the winds and heavens and perhaps even allow council with the stars once more?
