What happens if I play Stupefy on my 1 Might empowered Gangplank, Naval? Will he get +3 Might this turn?

He will not.
In order for his replacement effect to apply, the event of him being given -Might must occur. In the case of Stupefy played on a 1 Might unit, no -Might is given; it is snapshot to -0 Might. Thus, there is no suitable event for Gangplank’s replacement effect to replace.
