Each graphics object has a set of properties that provides sufficient 
information to recreate it. To make a copy you'll need to ...

(1) If the object is an axes, make the figure it is to be copied to "current". 
If the object is a descendant of an axes, make the axes which is to be the 
copies ancestor current.
(2) Create a new object of the "type" being copied.
(3) Copy the values of the properties that are both writable and have been 
manually defined.

It will take some study to determine how best to handle hggroups.
