Ellipse Packing from Circle Packing VB script component

So I am working on a skin and want to get it to be packed ellipses or ovals instead of circles. The component I've been working with is one of the common circle packing scripts floating around grasshopper3d.com, but due to my lack of scripting experience, I am not able to convert it to pack ellipses instead of if it is even pheasable to edit this componenet or just develop a new script. 

Below is the attached script.... i need this done ASAP so any help would be appreciated

thanks
