I did think of something like that but my idea was to add a 1mm thick thermal pad around the die. I actually just tried it with the Liquid Pro TIM but it was a little too thick and prevented die from making contact with block. I tried to thin it down but couldn't manage to get a good mount with it and my CPU would not post. Got an error 55. After about 3 on and off mounts with the error 55 I took off the thermal pad and then was able to post but still didn't have a good mount. Took about 5 or 6 mounts to get a good mount so now I am thinking about leaving it alone. I would like to try the Thermal Pad again but it didn't work out the first few attempts and mounting bare die is kind of tricky to get the perfect fit.
This is what my DIE looked like with the Liquid Pro and Thermal Pad around it.
This is what I used: Fujipoly Extreme System Builder Thermal Pad - 60 x 50 x 1.0 - Thermal Conductivity 11.0 W/mK
FrozenCPU sells it.
