Neither Roassal or Mondrian support this. I will probably try to add this to Roassal in the future. However, in the meantime, Roassal allows you to change the size of the node in many different ways. You can click on a node and make it grow. You can add new nodes inside. You can zoom into it (check "ROExample new zooming"). Let's try to think about a convenient alternative to what you would like to have.
