There is no reason to believe that GD11 glyphs can refer only to Sun, Jupiter or Saturn. There are other celestial rulers. In E a slightly modified GD11 indicates that also Moon is a ruler in the sky:

Sun			Jupiter
	Eb7-3	Eb7-4		Eb7-11	Eb7-12
Moon			Venus
	Eb7-5	Eb7-6		Eb7-13	Eb7-14
Mars			Saturn
	Eb7-7	Eb7-8		Eb7-15	Eb7-16
Mercury			Sun and Jupiter are here referred to by other signs than GD11, while the rulership of Saturn is indicated by a complex glyph based on GD11.
	Eb7-9	Eb7-10
