ebay has a ton of thinkpad scissor switch replacement keyboards for laptops and was curious if anyone thought about converting these for PC use?

It is certainly possible, but you need to reverse-engineer the matrix and use your own keyboard controller. On laptops, the controller is usually on the motherboard -- not included in the keyboard.
By the way, there are lots of cheap low-profile keyboards at very low price out there with USB. There have even been standalone Thinkpad keyboards available for desktop PCs.

Yes. I'm actually ordering one of those this weekend. But I've heard that it doesn't 'feel' like a real thinkpad. I've read recommendations of putting dynamat on the inside and adding a full rubber mat on the bottom.
So yeah ... I guess I could dig up some specs to see how those keyboards are wired out and then steal a controller out of a dead unit or a $2 rubberdome.

You can only use an existing controller from a cheap keyboard if your thinkpad keyboard has exactly the same matrix logically.
Membrane keyboards can't be rewired like mech keyboards to build some other matrix that a controller requires. If you want to reuse the membrane from the thinkpad keyboard, then in most cases you'll need a programmable controller like a teensy.

The only thing I like laptop keyboards for is donor plastic. It fixes broken Model M barrel frames quite well. I wonder what else I can fix with them...

As a long-term user of several laptops - I had to due to life style - I assure you, you don't want the "technology" of laptop keyboards to infiltrate desktops, especially those new flat ones.
In fact I have developed the idea of the 'mobile desktop'; it's basically a notebook without a mousepad and a keyboard with a perhaps shorter but thicker front so one can also put an external keyboard closer to it. [without the crippled technology of tablets]
Yeah.. I don't believe there's a point in not connecting a mouse and a keyboard to a laptop. And actually using a laptop on the road is quite a niche for the majority of people. Most of the time it's not used as a laptop but as a mobile desktop. [and the weight of a keyboard and mouse is negligible and they fit in a carrying case easily]

Logitech sells scissor switch keyboards, look into the Illuminated.
I kind of agree with Fateswarm.
Chicklet style is terrible, as is the overall flatness, but the bigger issue is durability. Those switches, while durable long term time-wise, are extremely fragile if anything is dropped on them or simply hitting them hard. I work on lots of laptops and I see busted keys constantly.
