[RPG] Can a Blood Hunter / Bard use Blood Curse of the Eyeless and Cutting Words on the same attack roll

bardblood-hunterclass-featurednd-5e

I've seen a reactionary curse that says you roll your hemocraft die to reduce an attack roll that you can see. Since this and the Lore Bard's use of Bardic Inspiration work mechanically the same via Cutting Words and uses a resource, could/should it be used in the same reaction to reduce a roll?

When a creature you can see within 30 feet of you makes an attack roll, you can use your reaction to roll one hemocraft die and subtract the number rolled from the creature’s attack roll. You can choose to use this feature after the creature’s roll, but before the DM determines whether the attack roll succeeds. The creature is immune if it is immune to blindness.

Amplify. You apply this curse to all of the creature’s attack rolls until the end of the turn. You roll a new hemocraft die for each affected attack.

Bard's Cutting Words

When a creature that you can see within 60 feet of you makes an attack roll, an ability check, or a damage roll, you can use your reaction to expend one of your uses of Bardic Inspiration, rolling a Bardic Inspiration die and subtracting the number rolled from the creature’s roll.

Blood Hunter's Blood Curse of the Eyeless

When a creature you can see within 30 feet of you makes an attack roll, you can use your reaction to roll one hemocraft die and subtract the number rolled from the creature’s attack roll.

Since both features require the use of your reaction, you have to choose one of them. If you can somehow take multiple reactions in a single round, combining magical effects would allow you to use both since they are different effects. As Peter Cordes pointed out in the comments, even Matt's Cobalt Soul Monk subclass which can have multiple reactions would have to choose one effect for the trigger.
