Alternative rear disc conversion?

[Neinris]

Alright, here we go...

I've known about this for quite a while, almost 2 years now. Not sure if this is more cost effective than swapping the rear axle with the 2012+ SE.

I've found this thread from another Toyota forum, and it's not even about the Yaris, it's a 10th GEN Corolla.

BLUF:
This involves installing bracket plates for the calipers to mount on. Part numbers of said plates/splash shields are 47803-02020 (right) and 47804-02020 (left).
IF these plates in fact fits on the Yaris, it could be a game changer. You wouldn't need to swap out the whole axle, and your wheels will stick out 10mm farther, which would then make the rear wheels stick out more than the front, which I don't mind.
I kind of wanted to be the first to do it, but I'm sharing it now to see if anyone dares to try it out, and I don't really have the funds right now.

I know most would argue that these light cars don't really need disc brakes in the back, blah, blah, blah... If you're not interested, you can stop reading. But for those who are curious, this might be worth your while.

Here are most of the parts that the other poster used for his rear disc brake conversion (my apologies, I can't seem to copy the table but I hope you can still figure out what category falls where):

P/N Quantity Price EA Description
0446602310 1 $ 40.88 Disc Brake Pad Set (Rear)
4780402020 1 $ 122.13 Brake Dust Shield (Left, Rear)
4780302020 1 $ 122.13 Brake Dust Shield (Right, Rear)
90947A2023 2 $ 46.13 Brake Hydraulic Hose (Right, Rear)
4782102160 2 $ 96.43 Disc Brake Caliper Bracket (Left, Right, Rear) Mounting, Disc Brake Cylinder. A bracket for a disc brake caliper.
4785002180 1 $ 150.51 Disc Brake Caliper (Left, Rear)
4783002180 1 $ 150.51 Disc Brake Caliper (Right, Rear)
4243102200 2 $ 53.31 Disc Brake Rotor (Rear) A single disc brake rotor
4642002151 1 $60.27 E-Brake R
4643002151 1 $60.27 E-Brake L

The big thing that I want to point out, P/N 42431-02200, has the same dimension as P/N 42431-52080, which is the part number for the 2012 Yaris SE rear rotor. Do I have your attention now?
So, first things first to get this to work, the splash guard would have to fit on the Yaris, if not, we're dead on the water. Next, need to sort out what else from that list can be used on the Yaris, well some are straightforward, the calipers can be used, and the pads, since the rotors are the same dimension. And finally, is this more cost effective than the axle swap? Probably easier to tackle than the axle swap, especially if you're by yourself.

There you have it Ladies, another stupid idea from me. I hope someone is crazy enough to test it out before me.
