That is the method I always used when I was using CATV hardline. As I recall, .625 fused disc line had the perfect sized center conductor for a UHF barrel. With .750 cable I had to file down the center conductor a bit. For .500 coax I would build up the center conductor by soldering on a short length of appropriate tube or the center pin from a PL259.

This technique has been used here for the last 20 years.

BUT I have used 3/4 inch 75 ohm CATV hardline.  Core out the
dielectric, slot the outer jacket, insert the PL258 double female
adapter, hose clamp the adapter onto the outer jacket.  Weather seal.
Don't forget the exposed adapter is open to weather so be sure to
mate with another cable (PL259) and seal that junction.

The center conductor of the 3/4 inch OD cable is just slightly larger
than the female contact of the adapter and makes a nice snug fit.
Use penetrox to insure good conductivity on both the center conductor
and the threads of the adapter.

I have done all kinds of attachment methods for 1/2 inch cable and
PL259's but it has never been as nice as using 3/4 inch hardline.
