In D2D, this is addressed with the gradientOriginOffset parameter:
"In the brush's coordinate space, the offset of the gradient origin relative to the gradient ellipse's center."

To support it, it would be straighforward to expand the syntax from (one proposal):
radial-gradient(<size> [at <position>]?, <color-stop>[, <color-stop>]+)

to (another proposal):
radial-gradient(<size> [at <position> [offset <length>{2}]? ]?, <color-stop>[, <color-stop>]+)
