Vifa OT19NC00-04 3/4" Fabric Dome Tweeter 4 Ohm
Does an 8 ohm version of this exist anywhere?
Would anyone recommend flush mounting these in a sail panel?
These will work fine for an application like that.

Is this the same tweeter as the vifa xt25 without the diaphragm? I have a pair of older xt25s that came with mounting hardware that I'd like to reuse
These use a similar dome style although they are not the same as the normal XT25 models.

first order crossower recommendation anyone?
If you are going to cross this with a 6 db/oct xover - a minimum of 4khz would be suggested.

Is there a practical, solid way to marry these to a Dayton Waveguide?
I have a pair of surplus Dayton Waveguides (270-316) that I've been looking to use in a pair of small cabinets. I'm intrigued by the idea of somehow marrying these RRs up with the WGs, but could use some insight as to how to do that in a solid, acoustically viable way. Hot glue? zip ties? Suggestions welcome.
The tweeter you are referencing is not designed to be used in that kind of application. It would be very interesting as an exercise if you had the measuring equipment to see the resultant changes in response, dispersion, time smear etc... But there is a reason that there is a threaded mouth - that is so the user will mate it with a driver specifically designed for a horn / waveguide etc...

How are you supposed to mount these?
I have an idea where a tweeter like this would work perfectly, but I'm not sure how I'm supposed to mount it. For my idea it would need to be flush mounted in some thin ABS plastic. The only thing I could think of would be to either glue some straps to the back or try to cut my hole so perfectly that it will fit by interference (though I don't think that's feasible). Could I use the wires to hold it in place?
There are pictures that you can look when you google or other wise search for tweeter waveguides. You can also mount these tweeters to cabinet surface from the rear by making the hole as close as you can the same as the tweeter front diameter is and curving the material from the thickness of the tweeter so that the curving starts from the front of the tweeter. The rate you can see from the pictures you find from the net to your liking. The mounting itself could be done by clamps screwed to the material and pressing against the tweeter frame from the rear. Because the tweeters are light, the clamps don't need to be heavy and three or four would work just find. You can even make them by yourself by using thin sheet metal strips and cutting them about 3/8" wide and about 3/4" long, drilling a 1/8" hole to one end and making shallow s-curve to them. Hardware store or hobby stores might also have what you need. You might find that mounting to ABS might be as hard than to wood maybe harder and you would not get any protection for the front of the tweeter as the center would protrude ahead the rest of tweeter. Particle board or any of the materials used on enclosures are quite easy to work with.
