Give me a valorite scribe's pen.
Be carefull about what you're asking for, you might get it.
Unless you enjoy the mindless grind that BoDs were
Anyway, what made the BoD system viable was the sheer amount of junk properties which made 95% of the crafted items trash food.
There's not so many possibilities with spellbooks, a maximum of 3 properties ensures you'll get something valuable pretty soon.
From a logical point of vue, a warrior or archer can get an undead slayer weapon in 15 minutes tops, why not a mage?
I'm in the process, ATM, to craft spellbooks to get the undead and demon superslayers I lack and after going through roughly 30.000 scrolls, I got 3 reptile slayers.
How many tens of thousands more to get the spellbooks I need?
I write 'need' since there is absolutely no other choice than using a superslayer spellbook against mobs who have from 5 to 100 times more hitpoints than vanilla mobs, unless you like being ridiculed by warriors and archers.
I suspect spellbooks are not treated the same as other imbuable objects, otherwise we would already have them, just my 2c.
Edit: Do not forget many players will vote 'no' because they already have their slayers and would not like others to have it easier. Human nature at it's finest.
