Just so you know where I was coming from, the following sourcing for the islands as part of N America:
 * "Composition of macro geographical (continental) regions, geographical sub-regions, and selected economic and other groupings" from the UN as of 2013-02-11
 * Encyclopeadia Brittanica

I can see an argument being made for the portion running along the norther edge of Brazil being lumped into S America - proximity and, IIUC, actually being on the S American tectonic plate.

That doesn't help with a fictitious island unless it has been consistently placed with the islands along the southern edge of the region.
