I lean toward the redirect it. Less likely to have any major ramifications and/or notice by Starfleet or the Callicans. Probably also the easiest... we are in a time crunch.
Also... there have alredy been issues with the memory banks on the Peregrine after Chimera, so whose to say that the earlier scans of the trajectory made by the Peregrine don't somehow become corrupted in the process of trying to fix the memory banks.... Oh Kennedy is just going to dig herself deeper and deeper...
But basically... who knows what the original trajectory was...
Once she's certain that Drake isn't going to throw her in the brig for lying to him she's likely to make that suggestion. I've just been holding on until she gets a pass from the Captain before doing anything further.
