I would not recommend this. There is a risk of breaking the newly loaded
sample. It seems optimistic to think the new tube will enter the first
spinner so that you can eject them both. If the tube does not enter the
first spinner, it may well break, and the first spinner will still not
eject.
If you have some 5mm diameter nylon rod, or similar, you could try the
process substituting this for the NMR tube. Or construct a long enough
rod of similar material to try and extract the spinner manually.
I have used pieces of 5mm nylon rod linked together to extract an empty
spinner from a benchtop permanent magnet system, but the distance
involved was much smaller.
