I made a list of Hymek liveries some time ago, though I didn't keep a note of the picture references then.
These are my additions to your list:
GFYE - D7016, 7029, 7075, and 7094
BSYP incl window surrounds - D7010
BSYP with white windows - D7041
I have 13 locos noted as fitted with minature snowploughs at one time or other, including those noted by Mark above.
Edit : I did think D7025 got BFYE, but I think this picture proves that to be false
