With France out of the equation anything could happen. Furthermore, it all depends on the peace negotiations who get's what. Guyana is loose change. Malaysian Borneo might be a bit far-fetched though I agree. If things go well for Von Lettow-Vorbeck (which is totally possible esp. if France and Belgium are out of the equation) there could very well be a Afrikaner rise up in South Africa.
With French out of the equation, the central powers only need to defeat the russians and if they aren't unreasonable in the peace, Britain will also make peace.
Not being unreasonable does mean that the central powers won't gain any British colonies (so no Dutch Borneo or Guyana), no independent Boer states, annexing parts of Belgium will be hard (although no completely impossible, maybe a split of Belgium between the Netherlands an France will be acceptable for Britain).
For the Netherlands to gain evereything it might want, you need to beat the UK on sea as well as the allies on land. This is very hard and might even be impossible. The addition of the Netherlands to the central powers certainly will not be enough.
