enchants that lower stats won't help.
It counts your base stats, not total stats. The ones you see in parenthesis.

Getting combat mastery down to C will make your CP go down about 5 points, then getting smash down to A will make it go down another 5 points, making novice FB your second highest, giving you 50 points instead of 60 or 55 (rB CM or r9 smash).
You'll also lose some base stats deranking those 2 skills, so it would go down a bit more.

Deranking production mastery will help, with -5 points per rank.
Magic mastery giving you higher mana, consider losing that too, for another -5 points per rank.

And don't forget to relog after deranking skills, it doesn't take effect until relogging for some reason.

And good luck getting all those skill capsules o_o
