Merge Two Surfaces into one:

Could one of you Surface guru’s take a look at what I’ve got here?  I’m trying to merge two surfaces into one nice clean uniform surface where the contours all run together.  I’ve managed to create a few Boundary Surfaces to get them to merge together but they don’t look very clean and uniform.  If you roll it back to the original Surface-Offset1 you’ll see the two original Surface Bodies I’m trying to merge into one.  I’ve tried just about everything I can think of to make this a cleaner merged surface but have been unsuccessful.  I’ve tried the Surface Loft with no luck, and can’t really get the Surface-Fill to work out either.  Is there something I’m missing?  It seems I can’t ever get the “Curvature to Face” to ever work.  That’s ideally what I think would want here.

So if anyone else has any ideas let me know.  I’ll keep plucking away at it and if I come up with something good I’ll post it.

Thanks, I appreciate it.
