My initial thought was something like this, which would keep the drawer centered, with very little play sideways, and like the ones in the rear, very little drop when extended to about 80%.
At this point, I am not sure the assembly will work, so when the glue is dry tomorrow, I'll have another look.
Obviously, this is not to scale.

If you want to do something, you will find a way.
If you don't, you will find an excuse.

By your own weights its 3.1 lb lighter, and thats without the front - or any kind of slide either.
Your math doesn't add up, no pun intended.
The math figures like this. The smaller drawer is roughly 18x18". With a weight of 6.39 lbs, that figures to .01972 lbs per sq inch. 6.39 / 324. (18*18=324).
The drawer I need is roughly 20 x 24", or 480 sq inches, and only weighs 3.74 lbs, for 480 sq inches.
Taking the .01972 lbs per sq inch, multiplying it by the 480 sq inches that I need for the drawer, and we now have approx 9.4656 lbs for a drawer built like the smaller one, but in the larger size that I need.
9.4656 - 3.74 = 5.7256 lbs difference in weight for the same size drawer.
That's how I arrived at the difference, for the approx same size drawer, which they are not, at the moment.

I did find out today, that painters tape does a decent job of holding things together, until I could get the assembly into the clamps to hold it until the glue dries.

Then it's just a matter of patience and time while the glue dries.
Doesn't someone make a glue with a 5 minute set time, and 10 minutes to full cure, for those of us that are in a huge hurry? Lol.
Yea, I guess not.
By the way, after over 3 years, who said I was in a hurry?

How about that stuff they advertise on TV that you set with a UV light ? Shows them attaching bricks to a wall and then people walking on them like steps after a few seconds set time. Here's an example from Amazon.... UV Glue

I think you're being overly optimistic, but hey - its your project!
Gotta remember, you still haven't added a front, which individually is the heaviest piece in the drawer, and will need to be bigger on yours. You also, again, don't have any type of slide attached, which, simply by your increased size, will need to be more robust with your bigger drawer.
In the big picture none of this will ever matter but it is amusing.
There are 24 hours in every day - it all depends on how you choose to use them.

In addition to the weight is the extra expense. I can buy 1/4" plywood for $18.00, and the 1/2" is about $60.00. I will need about 5 sheets for all the components for the drawers and the slide mechanisms if I use the wooden ones.
$90.00 vs $300.00. Yea, I'll test just a little.

Here is the first test fit of the drawer that I made from 1/4" plywood. It fits well.
After the glue cured, 90% of the flex was gone from the drawer.
After putting the drawer in with the test slides, there was very little flex in the assembly.
We'll see what happens next.
Always a compromise between price, weight, and quality. Pick 2 I guess.

Ok, listen up!
30 days means 30 days! It doesn't mean 6 months! Alright? Got it? Ok.
What does that mean?
Well, do you recognize this?
