Is it possible, or rather, will it be possible, for geneticists to cut out the extra repeats in the CAG sequence on the 4th chromosome, for Huntingtons, to rule out the chance of Huntingtons before it starts up?

No. If you are talking about replacing all of the sequences in all of the cells, the answer is no.
