Issue applying draft for a seal & combining bodies

Hi all, using SW'14 and been trying to apply a 1-2 degree draft to one body (as the seal) and then to combine it with another body, the base for that seal.

The model is a bit of a mish-mash purely since SW refuses to fillet where needed and because of the curvy non-planar geometry, almost run out of ideas on how to get these bodies right and into one body.
