Lore question. Hypothetically, if someone in the imperium were to make -through either sheer genius or a psyker ability that interacts with tech- a power armor model thats either

>even better than what space marines chapter masters use, practically iron man level
>worse than what the marines use but its so easy to make that one could outfit decent chunks of the imperial guard without too much drama

then how high up the chain of command or nobility would that person need to be to not get deleted and looted by the mechanicus and maybe the inquisition too?
