Curious question: Can AM4 be converted to LGA?

Hey, PC builder here. I've been pondering a burning question over the past few days: Can AM4 CPUs be converted to LGA? When the locking mechanism is removed, it exposes a bunch of pins that eerily resemble an LGA motherboard. Maybe with a little modification, kneecapping all the pins on the CPU in favor of just pads, and a contact plate, could it be made into an LGA CPU? Give me your thoughts on this. Thanks!

Can you take F-35 engines and install them into Ferrari with a few tricks?

Technically not impossible. This would just be grinding down the pins on a CPU and changing physically interface on a motherboard. It requires no fancy programming, reverse engineering, just route electrical signals to known place. However the madness would be in a single production of an AM4 lga pad for the motherboard. Doing it by hand would be maddening, and I have no idea if you could order such a thing.
And then. Realistically it's not going to work the first try. Nothing does.

I've learned that many times lol

Given enough skill and time anything is possible. The big question is what would the point be?

The contacts under the top plate of the AM4 socket are not even close to LGA contacts.
The AM4 socket has a bunch of V shaped contacts that the CPU pins slide into the wide end of the V and then the top plate of the socket slides when you close the lever, pushing the pins into the narrow end of the V where they make solid contact.
Meanwhile, in an LGA socket, the pins are a bunch of tiny leaf springs pushing upward to apply tension to pads on the bottom of the CPU. This completely different mechanical interface is not possible to adapt.
You would have to create a custom interposer board, and then you'd also have to design and manufacture a compatible socket, since no manufacturer has an LGA socket that is pin compatible with AM4.
Tl;dr: not a chance

No. You're talking about 2 completely different architectures.

Not really no. It's much more than just the CPU socket. There are several components on the motherboard that are designed to work around a specific CPU socket/platform. The lines in the board can be differently connected based on this. Then there's the chipset as well, the UEFI, etc.

Why and what for?

Straight up intrusive thought

With an extraordinary amount of research, prep, equipment, and hours and hours of work, you could probably manage to ruin both a CPU and motherboard trying this.

Fair enough lol
