It may be possible, people have tested thus far by disabling core, 2,4,6,8 this way they are not sharing the work load and in turn performance suffering. Now in windows 8 it will be entirely possible as it will be forcing as my treads into the first cores and deactivate the other ones, so in games it will play great then when using high treaded programs the last cores could be turned on when needed. Itís interesting but at the same time complicated and clearly not ideal for people who have technophobia.
Thinking about it, it could be possible, games typically have two very large treads, so allowing the first 2 cores to run at their full speed and the others can help out when needed, so disabling core 2 & 4 would help games as they no longer saturate the two primary cores while the others could help out in heavily multi treaded applications and the remaining treads from games. In doing this you won't have 6 core treaded performance but 5 core but games performance will be up.

They are visionaries.
Sometimes you need to take a step back before you can take one forward. Sooner or later Intel will need to go down this route, it's just AMD took it sooner then expected.
On the plus side dispite disabling some of the cores you are not loosing the cache so there is more cache available to the CPU's.
