I like the concept...it's got a lot of hooks.
Of course, I tend to use those hooks for various Evil GM
tm plot twists.

If the dad isn't in on it, you could do a lot of nasty stuff. Calling in a team of heavy hitters to get the girl back seems like a reasonable reaction. Also, whoever Daddy owes that debt to might see this as an chance to grab the girl for themselves.
You used the phrase "take out the bodyguard" and stated that they weren't supposed to kill anyone during the grab. Why just one bodyguard? Is the bodyguard a total badass? If left alive, is said badass going to go all
Man on Fire and hunt the team with implacable badassery?
And, of course, it goes without saying that the daughter should be an utter, unmitigated, royal pain in the backside.

Insisting on coming along, being a total pampered whiny git, and a massive liability that has their payday firmly in her clutches. Even more problematic, maybe she's on board with the idea of killing off Daddy, but when it comes time to do the dirty deed, maybe she has a change of heart - who does the team really work for? Mommy? And can they assassinate Daddy in cold blood while Darling Daughter is watching...not just watching but "on the team"? She could totally ghost them.
Oh, I'm liking this scenario more and more...
