It's been explained to you why there is no "variant", you are stubbornly refusing to accept the explanations, that is all.
Take the triliteral glyph "nfr": commonly it is written as a single glyph but occasionally you will see the triliteral followed by the glyphs denoting "f" and "r".
The pronunciation remains "nefer" and not "neferfer".
The meaning is no different whether they are included or not. Scribes often (but not always) added single consonantal glyphs to clarify the sound and meaning of the triliteral glyph, that's all.
The commonly held assumption is that single glyphs are there to guide the pronunciation of less common triliteral glyphs (although the example I have used - nfr - is a common one.)
