I think it is possible, but not particularly reliable, and I think a 0.0000000001% is not particularly far off the mark when you're dealing with an experienced lich or mummy. You could say that any class which can hide from a lich can do the exact same thing - in fact, I'd suggest that some classes can do it a lot better than a transmuter.
I do remember Pelrin, as it happens, who ran a gimmicky damroll transmuter build. I was a hero at the same time he was. His entire build's killing power was based off of neuro - if he didn't get permalag from neuro, he either got whupped on (exceptionally low hp relative to other mages) or the target walked away (his damage output was significantly less than a stacked warrior). Take away neuro and Pelrin might as well have been an NPC. Even if he had eagle staff I'd consider him free kills for the lich/mummy. If you'll check his pbf, you'll note that most of his kills came from battle (who had no possible escape) or Fortress (disproportionate number of newbies) which pretty much bears out with my memory. Not like he was a bad player, just his build wasn't very effective against prepared and experienced enemies.
