Also, the lower ABV (and the fact that I only had one bottle of champagne at my disposal) may have helped me avoid the morning-after (night-of?) unpleasantness others have associated with this cocktail.
... made my first DITA using Lucid and another inexpensive champagne... and it was not good. I could barely finish it. I'd be interested to hear what they think!

Well then, being that I've never been known to keep my opinions to myself... here it is!
Champagne (the real stuff)
Champagne was a very sweet wine really through the end of the 1800's. The first true "brut" Champagne did not make it's debut until about 1880, but the style was only really popular in England, somewhat in the US, and it did not catch on worldwide until after WW1. So it is likely that in the early days of the DITA, the sparkling wine used was probably somewhat sweet.
As far as mixing Champagne with another ingredient, it needs to be approached as a pair, not unlike a successful food/wine pairing. My personal opinion on pairing Champagne is that it pairs very readily with a great range of foods. In fact, there are only two wines, I am aware of that I think have the versatility, and range of styles necessary to pair through a multi-course meal, and one is Champagne (Riesling being the other). The caveat here, however is that when it comes to particularly assertive and spicy flavors, the combination of carbonation and acidity in Champagne works to amplify those flavors, desirable and undesirable. I have, more than once, read opinions that Champagne pairs well with spicy Asian foods, but in reality, I have never found it to be palatable with very spicy food.
So that being said, I think the DITA can not only be enjoyable, but can serve as a training tool to teach the taster to really take a detailed look at the absinthe one proposes to pair, especially if the sparkling wine is dry. I think any absinthe with an especially bitter un-sugared profile should be avoided with brut sparklers (a lesson I learned my first time out with a DITA, when I used an absinthe with a notoriously bitter flavor profile). Your reaction to the Lucid experiment does not surprise me. If you want to use a particularly bitter absinthe, I would do what many have suggested here, and use some off-dry or sweet sparkler.
To sum this up, I think absinthe selection is key, if one uses a brut sparkler. I'm looking at a list of 14 absinthes I currently have open, and I see 4, maybe 5, that I think would make a really enjoyable DITA, paired with a brut.
As to the "f### you up" factor, I think you need to be careful with these! Do the math... if you're using 1 oz of average absinthe, and 4 oz of wine, the resultant drink is around 20% - 22% abv, add in the carbonation and...
Concerning La Clandestine, you're reading my mind. I think this would make a great DITA, and be pretty to look at, as well. My two faves so far were Kübler and Vieux Pontarlier, both done with a quality prosecco. The VP was sublime!
