> Any suggestions Michael?

The way PaQ posted here:

is what I would suggest...

It does end up with a planar piece in the top part which does not seem to be an unreasonable result.

If you don't want to have a flat piece at the top there, then it will be a lot more difficult, you'll probably need to use a different program that has an N-sided patch tool in it for that case.

If you really want to emphasize very evenly smooth junctures above all else, then possibly t-splines would be best.
