shower thought: Variant Legendary Resistance

after reading some interesting discussion around Legendary Resistance, i had a shower thought i wanted to posit: instead of being an automatic success, Legendary Resistance functions like the 2024 Fighter's Indomitable feature. aka, it allows the monster to reroll with a bonus equal to its CR.

pros (?): this allows PC abilities to still interact with the saving throw (Cutting Words, imposing Disadvantage, etc) while still massively boosting the monster's odds of passing. makes LR less frustrating for players ? maybe ? hopefully ?

cons (?): makes Indomitable feel way less special.

does this have any legs whatsoever as a concept ??
