Tempting, but at the point I would be willing to give up arcane casting levels, I think I'd rather just go true necromancer or pale master.
True Necromancer requires you to go Cleric/Wizard ... and costs MORE caster elvels than Mystic theurge. At 20th level, you could be Cleric(3)/Wizard(7)/Mystic Theurge(10), have 13 cleric caster levels, and 17 wizard caster levels ... compared to Cleric(5)/Wizard(5)/True Necromancer(10), and be (at best) the equivalent of Cleric(5)/Wizard(15) for most spells, and Cleric(20)/Wizard(20) for necromancy spells.
Which means giving up a large chunk of spells (9thlevel wizard spells and 4th through 7th level cleric spells), in return for only a few extra caster levels with necromantic spells. *shrug*
Pale Master does involve a loss of caster levels and spell levels too, yes - but if you went Wizard(13)/Pale Master(7), you would cast as a Wizard(17) as far as spells-per-day, and would only give up the final, end-stage Pale Master class abilities.
My last character was a fatespinner (very fun to roleplay) and I missed ever getting to cast higher level arcane spells. Since I've never (in many, many years of playing) cast spells over 5th, I really wanted to make that a priority.
Then simply never give up more than 3 caster levels. That, sadly, means forgoing beign a Lich (LA +4), unless your GM is willing to let things stretch into Epic levels - you'd get 9th level spells at ECL21. Which is truly a shame, because Lich is *such* a thematic template to add, as a necromancer!
