That is a strange question, but I'll give it a shot;
The .30-06 is a fine cartridge, but it will never be a .338 Lapua. The Lapua cartridge is longer and fatter than the -06. You may have a magnum length action capable of accepting a cartridge as long as the Lapua, the bolt face is much different. Changing calibers would involve a barrel swap and a new bolt.
There is no way a -06 can be loaded to be in the same class with the Lapua
In life, strive to take the high road....It offers a better field of fire.
