Route from Alpha Hut to Eastern Hutt Hut

Hi there - Im off on my midwinter trip soon and am changing plans to spend as little time on the tops as possible - there is snow forecast down to 1400 m soon - but the freezing level will stay at about 1900m Anyway i was planning on getting to Elder Hut from the Kakakapanui side, then to Alpha (top) and then potentially down the ridge that starts at approx E 1790398 and N 5459496 and ends at he junction of the Quion Stream and Eastern Hutt river. This site seems to describe that ridge and it appears straightforward: https://trippytramping.blogspot.com/2015/04/alpha-via-eastern-hutt.html Anyone done this? It will save me time to go this way if possible - rather than down Quion proper and then backtracking to eastern Hutt hut. Im also aware Im not meant to stay at this hut - just want to bag it...... Cheers!
