I'd be alright with it if we were able to take a few liberties with the design

    AT-PT

AT-PTs were made to take single troopers into intense combat situations on their own. They stood only 3 meters tall, and were driven by AT-PT pilots. The AT-PT is lightly armored, armed with twin blaster cannons and one concussion grenade launcher that is only effective against infantry. The AT-PT has superior speed to make up for its light armor.An AT-PT. The AT-PT was designed decades before the Clone Wars, but during the Wars the Republic found a need for a small, anti-personnel walker, and the AT-PT became more relevant. The AT-PT was a limited production model, the majority of which were stationed aboard the Dreadnaught-class cruisers of the legendary Katana fleet, and many were lost when the fleet itself vanished. These walkers, along with the fleet, were rediscovered by the New Republic, and were used in the Republic's war with Grand Admiral Thrawn.
The Galactic Empire still utilized a limited number of these walkers, as did the Rebel Alliance. They were often used as sentries and patrol vehicles near Imperial installations.

AT-PTs served as part of Blizzard Force during the Battle of Hoth in a rear-guard role. Large numbers would be used in the Battle of Ralltiir, where most of them were destroyed by Luke Skywalker and Rogue Squadron.

                                                                                 AT-RT

The AT-RT is 3.2 meters tall and 2.9 meters long, with a saddle-like seat for a single clone trooper. Its open cockpit-design makes the driver especially vulnerable to sniper fire, but low costs and good visibility of the battlefield makes up for this shortcoming. The recon walker is equipped with a nose-mounted repeating blaster cannon and mortar launcher, making the  AT-RT a capable anti-infantry unit. The AT-RT is fitted with a motion detection scanner and sensor equipment capable of providing Forward Command Centers with updated situation reports from the battlefield. Due to its light construction, AT-RT walkers are especially vulnerable to heavy weapons. AT-RTs are mostly used as fast scout packs or in the role of civilian (police or military) support. Commonly, AT-RTs are used as picket and pathfinder units. AT-RT walkers were deployed during the Battle of Kashyyyk, and were later used in an attempt to track down Jedi Master Yoda following the transmission of Order 66 as well as Outer Rim planets such as Utapau and Mygeeto. These light-weight walkers were also utilized in the attack on the Jedi Temple. Over a year later, during an attempt by ex-Jedi Fy-Tor-Ana and Ferus Olin to retrieve a cache of lightsabers from the occupied Temple, AT-RTs backed up teams of stormtroopers that were hunting them. During the Galactic Civil War, modified AT-RTs were also utilized by the Rebel Alliance and fringe groups. Many of these walkers were painted with camo to better blend in with their surroundings. A floodlight often replaced the repeating blaster cannon, providing additional aide for the walker on night-time missions, but making the vehicle more vulnerable in the process.
