With regard to the rubber hydraulic lines. A good hydraulic fitters would be able to remake / recrimp them I would think. many have mobile fitters (for lorries and the like). I would guess they would be a bit cheaper than the Porsche option! If you have the whole length of pipe then you could take it to them as a pattern.
I had the low pressure side pipe burst on me (split crimped end) Jubilee clip working fine.
