Actually, with the right tools and a bit of skill you <i>might</i> just be able to convert two single-sided 16-bit RDRAM sticks into a 32-bit RDRAM stick with a similar procedure.
The real question is why anyone would bother.
Me personally, I've always wanted to see if you could use the heat spreader connections to mount a thin water block across single-sided memory sticks. Imagine the memory OCing you could get with a setup like that.
(Of course, you'd also probably want a waterblock mounted on the northbridge and the CPU as well. Heh heh.)
