Update Line Z value from Points

I have a line feature with z enabled, but no elevation, it is a 0.  Each line has 2 vertices, one at the beginning and one at the end.

I have a point feature with z enabled and have elevation.  Each point is at the end of each line.

 

How can I add the point elevation to my line elevation?  I have tried a one to one spatial join.  That only gives 1 of the point's elevation data.  Which leaves me with a flat line, and not a sloped line.

I tried a one to many spatial join.  That gives me multiple lines with only 1 elevation.  I tried Points to Line, but that seemed to miss some of my points and not connect them correctly.  Update Feature Z will only accept a surface.

What workflow is there that can accomplish my goal?  I have access to all the extensions.
