I own an AT-AT from when Wizards of the Coast had the license and last night played a "Battle of Hoth" scenario with it.
I had to invent the stats and how it moves, and movement is what I want to share.
The first thing I did was to take some extra order tokens and put a little sticker on it that said "AT-AT move".
When that token came up the only thing the AT-AT could do was move. No other actions.
Next I had to figure how to get the templates to work with it. In the next 4 photos I will show forward and a something we can't really call a right turn, but it did drift to the right a little bit.
I designated the right had corner as the spot to set the speed 1 template.
(See photo1 with a speeder bike for scale.)

Next I moved the model to the front of the template. Often I put my finger in the spot one would normally place the rear of a model at then slide the AT-AT to my finger. (see photo 2)
and now the same concept but a drift to the right.
(See photo 3)
and now the ending position of that.... it will have to be in a comment as I've exceed the memory size...
I'll share my invented stats for the AT-AT after another play test. Last night's game showed that I made it way too powerful.
If you've invented stats that seem to work in a play test please share.
