what about bringing the ingenuine hoi3 research system to victoria with some modifications ?
Wouldn't work. HoI3's system is more geared towards post-WWI military research, which was funded and conducted by the military. Victoria doesn't focus on the military and is set in an era where most of the things were invented or discovered by individuals rather than were researched by and for the state; this is where the original tech system excellently fits the era and scope of the game.
