Genetic engineering tiering

[Anonymous No.10902681]

Does this seem like an appropriate ranking of difficulty?

T1: Turning genes on and off.
T2: One or a few promoter/protein modifications.
T3: Modifications that make changes to microstructure of the body, such as cell behaviour, arrangement, and form or even creation of new specialist cells.
T4a: Structural modifcations to the body that can be expressed even if the modification was performed on an unmodified adult human.
T4b: Structural modifications to the body that can only be expressed by those sufficiently early in development, except with suitable modifications to body maintenance.
T5: Metastructural modifications to the body; that is, what kinds of structures are created and where. Can only be expressed by modified zygotes as metastructure is locked in very quickly, except with suitable modifications to body maintenance.

T2, T3 and T4 can also be more specific with "h", "x", and "o" variants, standing for "homo/human", "xenos", and "original".
This refers to where the modification comes from. h comes from the same (or a very close) species, guaranteeing compatibility. x comes from a more distant species. o is of our own design.
Obviously, h, x, and o are easy to difficult in that order.
T1 and T5 are always h and o respectively, so this variation isn't specified.

An example of each modification tier:
T1h: Turning on the gay gene
T2x: Producing chlorophyll instead of melanin in response to sunlight
T3h: Increased bone density
T4ah: Making your hair follicles denser and thicker
T4bx: Changing your ears to become catgirl ears
T5: Adding more limbs

The reason for having such a tiering system is that it holds immense predictive power for the future.
If you know what a tier requires, you can predict when it will become available.
If you then assign a modification to that tier, you then have a good idea for when it will become available.
