There probably aren't that many folks making ribbons from scratch. I've done it in the past and it's fun but tedious. I think your method of corrugating the ribbon with ribbon cable is clever. I never had a good way to do it when I was building them, but then my ribbons were three feet long and made of foil strips on kapton tape so they didn't take the corrugating as easily anyway.
Keep it up.

Probably not, I agree I also think many people find it to be too much of a hassle, or maybe doubt their ability to make good ribbons.
Sure it takes practice, but is easily worth the effort.
I'd like to see a dome tweeter last as long as a ribbon tweeter, in the end it all comes down to serviceability, the ribbon is much easier to replace, then re-foaming, 're-doming' a dome tweeter, with planar or ESL it must be close to impossible.
Maybe you'll spend a weekend once in a rare while, making ribbons, but a good set should last years if you don't blow them.
With short ribbons such as the GAMMA VLD-12/13, or the DACCA DK30/London it's not too hard once you learn how to handle the delicate ribbon.
I can even move my ribbons from tweeter to tweeter, thanks to the silver paste which never dries completely.
For long ribbons, this is needed:
I have seen variations of this device on the bay, if you make a sort of guide, that forces the ribbon to enter this device at a right angle, you should be able to make ribbons as long as you like.
Maybe you could build the guide of cardboard.
How did get foil strips on to kepton tape, DIY or prefabricated?
That would make a kind of mylar, I would like to experiment with mylar type ribbons.
I'll keep going until I'm done.
