The way you propose to make a 6-sided bicubic patch requires stitching
together 3 bicubic patches so their corners meet in a point. As you can
read in other posts in this thread, you can't do that and still have a
smooth surface.

There is no way to create smooth n-sided bicubic patches from 4-sided
bicubic patches.
