DNA sequences are easy to clone more of, even today. Simply insert them in the proper sort of bacteria, culture for a few days, and you'll have all you could possibly need. This would be the first thing a professional genetic engineer did with a valuable but limited sample. Depending whether or not the BGCverse is up to landing their modifications in particular spots in the genome (it's about an order of magnitude or more finer than the sort of things Leontophus and Sylia's father's work did), the 'back to human' stage may even be safe rather than fraught with the risk of terminal cancers the way modern technologies are.
