I don't really wanna point out the arguments that speak against it, I have done that a couple of times in this forum.

Let me simply point out the bassics:

Codex Astartes is written after the Heresy, that is the only document that forms the basis of combining the different strategies of the Legions. All fought differently and had different ideas of how to act and how to work. As guilliman himself states: there is no basis for the unification of different Legions under one command.

all legions have their destinctive methods and modus operandi, which creates friction when they work together.

also. smurfs are the most numerous and have the largest recruiting pool by default, why not bolster the far less numerous legions like SW,EC,Salamanders and so on, or the depleted forces of IH and RG ^^

Immuno suppressive drugs would leave the receiver in a very weakened state for a long time, looking at f.e. the Bloodraven books, there is the process of transformation described, same goes for "deliverance lost2 or the first chapter of "scars"
