Family snaps to gum bichromate

I would be grateful for guidance on this topic (details of which are covered in the archives I know).
Among my 30+ years of family snaps are some that I see as potential 3-colour gum pictures, about A4 size or maybe slightly bigger.  Many of the surviving 6 x 4 prints are tatty and faded (and some have been re-worked in what appears to be an expressionist manner with felt pens, scissors, etc).  Most of the 35mm negatives are pretty good.
Would anyone in the group like to recommend whether I should produce the necessary negatives:
1.    Taking the best negatives to be scanned by a photo processor -  I have been quoted a resolution of 1200 dpi - and use Photoshop to make colour separations, or
2.    Get some more 6 x 4 prints made by a photo processor and scan them myself at something like 400 dpi, and then use Photoshop, or
3.    Make colour separations myself on document film using a slide copier and filters, and enlarge them on to lith film.
