Have you considered trekking poles?. There is no rain gear i.e mvp poncho or rain suit. Would you consider taking a folding Thermarest if the hammock doesn't work out or there is no suitable areas to rig up the hammock i.e no trees suitable. For an extra 450 grams, you could have much more flexibility where you camp. You could then use the trekking poles to rig up a shelter with the rain fly.
