The alternative would be to upgrade your rack to a Super Tourist rack, put the extra battery in the bag. Your battery will have no problems fitting into your existing DX bag.
Then move your current items into panniers.

The alternative is to get a trailer and throw everything into that; batteries, clothes, etc.

There's a lot of those racks on the market. You can even get a rack/battery combo from many sellers.

The simplest solution is to use J.R.'s suggestion. Remove the existing rack from your Trek and replace it with a double layer rack which will hold a flat battery. The trick is to find a double layer rack that will allow you to use your quick attach Topeak bag.
I did something similar with my Pedego Interceptor where the battery is mounted under the rear rack. The double layer rack idea won't work since the Pedego rack is not removable. I had to make my own. In my case, I have a collection of Bontrager / Electra quick attach bags which I use on my Trek MTB's. I made an "adapter" to hold a second battery and allow me to use my Bontrager accessories.
I made an aluminum battery box and mounted it to the top of the Pedego rack using insulated cable clamps. No modification to the bike was necessary. I chose to use a second OEM battery and just swap them instead of using a switch.
Next, I cut the top off an old Bontrager rack and mounted it to the top of the aluminum box using the same clamps.
I can now carry a second battery and use my Bontrager quick attach bags.
When not carrying a second battery, the box can be used for other gear.
The same design can be used with Topeak or almost any other brand rear rack system.

I understand that but I would like a rack with the bottom for battery and the top for the detach lock.

If you had used two panniers and put the batteries in the bottom of each them closer to the axle center it would have handled much better, albeit no lighter.
I have this now. I would like one with two plates.
I could do this with my rack I now have but would have to raise it up with leg extensions. I saw leg extensions somewhere.

Your idea of using leg extensions to raise your existing rack would work but you would still have to fabricate a battery mount underneath.
If you haven't already purchased a second battery, you could save some $$ by using J.R. 's suggestion. Buy a double layer rack / battery combination, then cut the top off your existing Topeka rack like this:
Then mount the top of the Topeka rack to the top of the double layer rack using insulated clamps:
I've used this idea on several bikes to adapt rear racks for use with other rack / bag mounting systems. The trick is making the adapter sturdy by using the correct size clamps for the different tube sizes.
Although the clamps can be purchased separately in hardware stores or home depot, I found it easier to use this assortment pack:

As soon as the weather gets better I will do something. I just want to use theTopeka bag on top with the quick realease. Lowes has the flat chrome like metal that I can build the box with.

What are you people talking about! i got most of my accessories from the dollar store. I just put 16 kms today at -5 c on a cheap Chinese frame mounted 450 watt motor and 24 volt, water, slush everywhere. 30 amp hour LG battery in a basket, i still have lot's of juice left. I did very little peddling. Side baskets $4 each, rods welded to the frame to secure the basket $2 each. The side baskets attached with zip ties, $2 a pack of 40
I do have a mini welder, that helps but seriously e-bikes can be done cheap!
I'm going with a rack battery and a frame battery, 2 totally separate systems. If one dies i have the other plus i only have to replace one pack, half the cost
