T series keyboard + Palmrest

Hiya everybody
I've just recently purchased a Vaio T270 alongside with my order of the SZ791N/X as I wanted something extremely portable as opposed to my SZ (but with a readable screen; which was why I didn't buy the Eee PC, but maybe the new version)

Anyways, I bought it used, as I didn't want to chip out $1400 just for a secondary laptop, and the keyboard shows signs of wear, and was considering replacing it.

But then I prefer the aesthetics of the TZ and TX keyboard more (TZ>TX though), and was wondering if I could actually replace the individual keys on them since I know that the keyboard itself won't fit.

I looked it up, the pitch and stroke are the exact same (i.e. width and depth), and was thinking that the TX might be able to, but if the TZ was able to, it'd leave a gap inbetween the keys, like in the TZ itself.

What I was wondering though, is if it would even work at all; if the clipping mechanism would either fit, or be completely compatible with the TZ/TX.

Also, about the palmrest; it also shows that it's been worn down, and was wondering if there was any difference in the palm rest between the T150 and the T270; From my point of view, I can't really see any, but the structure may be different and might not even work. But from my recollection, the T150 and T270 laptops are almost identical.

Summed up, would the T150 palmrest fit the T270?
(i can only find T150 palmrests)
