It's really not a question of G1 or not but of what you feel would work best. While we were more or less introduced to them having them pair off against the Dinobots, The Dinos were also paired in some minds against the Incecticons. (which would make interesting repaints)and SG Grimlock has already been shown to have G1 Trypticon's palette.
The color scheme they (well the two we saw) shared G1 Protectobot colors (which makes sense in that they would be healers) they also share the colors of G1
Halo So SG Devs would match against that quite well.
Regardless, make what you want to make, and post that bad boy up when you are done, as regardless the colors, the odds are it will look bad ass either way.
