Siamesing L98 TPI Base Manifold

[Hardlight]

Has anyone experience with siamesing the adjacent ports in the stock L98 intake base? Looks like each cylinder will get to pull from two runners at a time instead of just one. Thats a lot more air than just one "large runner"at a time if you went with large runners and different base (Big Mouth or Accel) manifold. If you ground the walls out in the manifold yet kept the resulting inside runner lenght (in the manifold) to the valve at least 3 - 4 inches, will this be satisfactory?
