I don't have any special insider information, but from what I know about spaceflight I think we should be glad they used the Falcon Heavy instead of SLS. SLS has been consistently delayed pretty much every year since its conception, most recently the Artemis 2 mission which was supposed to fly this year is now delayed to next. It has only flown one time, now two years ago. It's also an order of magnitude more expensive than the Falcon Heavy with each flight costing upwards of $2 billion. My guess is if they had been stuck with SLS this mission would not get to Europa until significantly later, if at all.
