I would assume the mostly white body comes from the w2 and the large white factor contributes to how the w2 is expressed. As the stallion does not carry w2 you would be able to GMT that off, which would decrease the white.

This is one of my mares that carrries w2:

ZX IV Oblivious Wish

To compare with another one of my mares, who is a Buckskin Splash also, but without the w2 gene.

ZX IV Silver Quest

You are also able to GMT the WF down to 'minimal' which would increase the liver chestnut coat by decreasing the 'loudness' of other white gene expressions. Hopefully this makes sense!

w20 does not usually produce much white on the body, if any, so I would not think that would need to be GMT'ed.

In regards to the Kit Promotor, it only presents when it is homozygous (two copies of the gene) as it is a recessive gene. This colt is only heterozygous as his dam doesn't carry the KP line, so he carries one gene.

I'd use the search to look at different combos of those genes before GMTing to make sure you get the result you want.
