Don, you could bolt on extensions to your cabane points, (think steel landing gear straps only smaller), and then attach your landing wires with a bolt through the wire loop and extension. If all bolts are small, they shouldn't be too obtrusive. The easier alternative would be a quick link on the inner end - not scale, but easy and you never see it in flight. Come to that, you could also use a MR clevis end as your wire terminal - smaller but more fiddly.
