Re: Wondering: is there any way to change the lichcraft spell...
 

No? It's a fairly decent spell as life insurance for your death mages. As a bonus sometimes they gain extra D after dying.

A bit too expensive for mass use, though. I tended to use it on death wizards who had gotten diseased.

Then again if my wizards are plagued by old age I like to keep GoH handy. And that solves the problem

Yes, it solves (part of )disease problem. I also used it once on mages who were casting distant damage spells on provinces with quite possible (Fire) Domes. It worked, too - enemy blasted, damage coming back and burning my mage - and he just raises again as a Wight, with higher stats and no upkeep as an added benefit.
As for Twiceborn solution - I would prefer to copy spell stats in this case to save Twiceborn as is, adding Lich as another variant. Am not sure whether this would work, however.
As for cocktail - does somebody know whether any news from code divers had appear lately. I have one old version, but maybe something new exists?

Yes expensive mages can have some high upkeep costs and twiceborn usually gives the mage stronger stats and no upkeep. The twiceborn also works on pretenders, especially useful for rainbow mages which are generally weak.

Simply change the description of the lichcraft spell...

"With death and a new life the mages has taken a new name and risen in thei service of the would be pantokrator....."

then chain the spell "kill me"

No, because the point is in keeping the paths and special skills.
