I cannot imagine a situation where this would be worthwhile.
You can work up a Silver Flame Talisman in about 30 min to an hour if you have an opener for the Cursed Crypt, or about 3 hours if you don't, which covers most situations that you'd need Death Ward in, but can't rely on the spell not getting dispelled.
If you TR at all (still), you can acquire one of these per life. So far, I have only once run through 20 charges before getting to shrine. It's hard to imagine spending that much effort to twist in something that is easily replicable by a level 7 clicky that you can have as many copies of as you like, festival cookies, party members, or a level 11 item, especially with so many stronger options available.
