You do not need to do this because your GPU is actually doing this for you: What is not inside the available VRAM, it will be loaded from the RAM or if not there, from the hard disk.
If something is loaded from the hard disk, there is risk of experiencing a mini stutter.
If (very common CoD situation) your VRAM is full, your GPU starts unloading things from the VRAM in order to mae free space and load the additional things.
If this is a constant situation then you will notice that easily, your fps will usually drop to 50% of what you usually have.
The reason for the drop is that loading data from the RAM (or even worse the hard disk) has to go through the motherboard circuits (your PCI Express) and it is much much slower than the ultra high speed VRAM (nowadays GDDR5 class).
In short: Your idea is clever but unworkable as it will not deliver the performance you hope for.
On the other side, if your problem is on the data handling from your hard disk to the VRAM, creating a 5-6Gb RAMDISK and loading most game files there, will solve your problems.
You need to have 12-16Gb RAM on your PC in order to do things like that...
