Sounded real good Sean. Tone is in the hands and you got the hands for sure
I think you are right about the actual guitar making a difference. Mark's Divebomb inc. Franky strat was a heavy MF'er. I recall he mentioned it was about 7 lbs, body alone

So thats a very TIGHT/BRIGHT sounding guitar and Mark initially slapped his trusty '59 pu in it and declared it a "Thin" sound. It took a DSD to make Mark like that guitar, so yeah, IF you had a (heavy) ash strat with a DSD in it (also, a reissue Fender 6 screw trem, which is brighter/ tighter sounding than a Gotoh), you would be as close to Marks Mod5 tone as humanly possible.
I think YOUR style is better represented with the Bray Marshall though
