Also, I can't say I particularly advocate merging any two bloods currently. All mage bloods do share some concepts and similar functions even across different magebloods, but actually merging them across bloodlines will require us to rebuild Blood from it's magical foundations, which means a lot of retcons. I do think they need more specific work however, in order to give each variant unique flavor and abilities that can't be copied by other mage bloods (Which is also why Inferno Magic needs revision since it is capable of bastardizing at least elemental mage bloods).

I'm not too thrilled about that myself. Namely as we talked about something similar, which is the end results and how each blood can achieve them in different ways. Take Electromancy and Pyromancy. They both can fry you but the way they do is different, Electromancy uses electricity to basically nuke you while Pyromancy literally burns. Both result in burnt meat, but not in the same fashion. 

Another example is the insect control for psychomancy and herbamancy. They can manipulate insects in different ways through either mind or scent, causing them to attack enemies in similar ways or follow a set of brain patterns based on instinct. Either way, your foes feel the sting of those little beasties. 


Final example, Vitamancy and Noxomancy. Both can weaken the body, Vitamancy by starving the body of needed nutrient and forcing it to reject them. Noxomancy by slowly rotting the body from the inside out or causing sickness to attack key aspects of the target's body. Again, similar effect but different ways to get it. These aren't the only bloods that does this but these illustrate my point that bloods can technically mingle when it comes to getting a set goal/outcome if you're creative and reasonable with it. Mainly reason realism does play a bit of a part in these magics.
