is it possible to use sprites to stack zerglings?

Example

You just want to know whether or not it is possible to stack zerg units, or whether or not you can stack zerg units sprites?

Also, are you going to want to know how to do this trick, if it's even possible, or are you going to be asking for an example map in which to learn from?

You should probably also take the time to read through this before posting another topic. http://www.staredit.net/topic/3639/

To be honest, you could have just asked this question in the shoutbox. I tried using the search function and found only a mod that stacks units, so you couldn't really have broken rule four, but you definitely need to put some actual effort into number one and two for future posts.
