May I request a mod that makes "nature's beauty" give a temporary charisma bonus?

It seems very impractical that a spell that makes you look attractive enough to blind people not actually make you attractive.

It's a level 7 spell in the priest book learnable by druids.

From the wiki:

Nature's Beauty
When this spell is cast, the caster appears to undergo a remarkable transformation. The caster becomes the very ideal of beauty: For a male, this is usually a nymph; for a female, it varies. As with a nymph, anyone viewing the disguised caster must make a Saving Throw vs. Spell with +3 bonus or die of longing for the denied illusion. Even if the Saving Throw is successful, hapless viewers of the transformed Druid are all instantly smitten with permanent blindness (until dispelled). The transformation is instantaneous, but lasts only seconds, affecting those near the caster (excluding fellow party members).
