We've seen that people with two different powers have quite a bit of power and quite a bit of control. Itachi for instance couldn't just cast Amaterasu, he could also stop the flames. Sasuke on the other hand needs Kagutsuchi to do that.

In fact, it seems to me that when people have a dual power, one eye is refined for power and one eye is refined for control.

Sasuke: Amaterasu can cast flames like Itachi's, but can't control it. Kagutsuchi can shape the flames but not cast it. Kakashi/Obito: Kakashi's Kamui can project a spacetime barrier over a distance. Obito's Kamui only works on himself and objects he touches. However, he can create complex barrier shapes to partially transport himself for intangibility. Shin: Shin's ability is essentially Kamui, but as a one-eye type power he can cast it centered around him while extending the field further. Shishui/Danzo. This isn't very clear. However it seems that Danzo possessed the Control type eye (subtle manipulations of the mind) while Itachi's crow possessed the Power type eye, which could issue direct commands("protect Konoka"). (and so, Shisui could force people to do things while making it seem like their idea).

Sasuke is the odd one out, but he named his technique himself. In a sense he simply has Dual Amaterasu.

It's then difficult to see what exactly a Dual Tsukuyome would be. Maybe it would split the powers over Genjutsu Space and Genjutsu time, with refinement for both?
