Can you do as @Julien said until the offset shapes overlap, then combine those shapes. I don’t use create, but that’s how I’d do it in inkscape or similar.
@nathan32935 How large an offset do you want? I do this frequently by making the offset large enough to get a single outline, delete any islands the offset inward to get the spacing desired. Sharp detail is lost but you can modify the vector if desired.
Like Lester said…
if you select all your vectors and then group them, then offset them as a group, it will get 90% correct and then just a little cleanup and you are good to go.
