Do I think it's likely that their shinies look like mine? Possibly. Definitely not exactly like mine, but I tried to think of a logical shiny for the two of them.
Changes:
Gold to silver
Primary color (blue or red, respectively) to black
Secondary color (red or dark blue, respectively) to red and light blue, respectively
Black on face and claws to blue and magenta, respectively
And I left the snout and legs the same color.
SO BASICALLY it's a complicated color swap with silver and black.(Personally I like Zama's better because I did that one second, and also the silver and black are darker that Zaci's.)
