Professor's guidance for leadership benefit if you can't modify

[soundandshadow]

If Gambit makes an attack against Black Cat, during modify dice step can Professor X pay 1 power to use Professor's Guidance. Gambit then MAY reroll 0 dice because no reroll against Black Cat.  Gambit then gains 1 power from Xavier's School for Gifted Youngsters leadership.    Does this work?   It seems to since professors guidance says first spend power to use this superpower.  There is then a period. Then a second effect (modifying dice) kicks in.   Additionally, can you choose to spend power for a guidance superpower and then to not reroll (maybe you have all hits) so that you can use the leadership? It seems like you can since it says attacking character MAY reroll 1 of its dice.
