Does Project Necromancer Make Rey’s Dad?

This is where things mostly get speculatory. We know that Rey’s father, Dathan, was a strandcast clone that disappointed Palpatine with his lack of Force sensitivity, and Hemlock does mention to Palpatine in Bad Batch that Necromancer has already produced one “successful transfer,” albeit with a low M-Count. Could this be Dathan?
Palpatine’s son was “born” in 12BBY, as far as we currently know, so while we don’t have an entirely definitive time frame for The Bad Batch’s third season just yet, that could be a little too late for the chronology we’re working with here. Maybe things could be fudged here to make that date still work; perhaps Dathan was created on Tantiss, before being sent to Exegol in his youth after Palpatine grew frustrated with his lack of viability?
