Just putting some feelers out to see if anyone else would be interested in heading up.
In the past I've done 2 nights at Macaulay with a trip up to Godley Glacier and back on the 1st day and out and home on the 2nd. Could be done with one night if starting from nearby or maybe a night at Macaulay and a night up at Godley (last bit on foot) or Red Stag hut.
Even one night in there and one up the Hopkins down the road would be doable depending on peoples pace preferences.
Fuel wise the 2 nights at Macaulay is about bang on 200k from a Tekapo bowser start and finish.
It's mostly grade 2-3 and the river crossings are the only potentially tricky parts depending on rain/luck.
