how about eye of Heaven or what you may call it- gives him better control of chakra- gives him the perception just like six eyes of gojo- gives him heaven defying analytical abilities- can analyze all known and unknown information/phenomenas and make him use them as long as the essence of the abilities are analyze (like great sage/ciel analytical abilities)- parallel thought processing
Bro, each rinnegan user has a unique ability like madara, sasuke, urashiki and others, with that in mind, why don't you make the tenseigan also grant a special ability? there you can include some of the ones you showed instead of creating a new dojutsu. Besides it would be better because you would already have the default abilities of the tenseigan (Golden Reincarnation Wheel Blast, Silver Reincarnation Wheel Blast, Truth Quest Ball, Tenseigan Chakra Mode, Shinra Tensei, Banshō Ten'in, Chibaku Tensei, being able to control objects like Toneri did with puppets, etc.) bro you said it yourself, the tenseigan has not been explored to its maximum level, you have so much to explore that it makes no sense to drop it.
in the eye of the byakugan that evolves into tenseigan while the other is the 6 eyes of saturo gojo gives him the ability to manipulate space time and I honestly do not understand your insecurity with the tenseigan when it gives the user different abilities: manipulation of gravity absolute is not like the rinnegan is literally gravity manipulation, 5 element manipulation, tenseigan chakra mode, gudoudama creation, ying yang manipulation, great ultra violet vision and all the types of vision you think of. That's not enough for you?
Author-san know why most writers make Naruto more fanfic than Boruto? Because in Boruto the powers of many characters are broken to no more power, this makes giving one or more powers to the Mc more complicated because if given a simple power, will make in the long term the Mc not of great importance in the battles to come and if not by doing it too op will make it seem that he can resolve things easily or without striving
