Lonicera hispidula should be possible.

ditto bboy...those things grow without any help at all, and the flying life love them :)

Characteristic of Douglas fir/madrona/salal association on bluffs etc. near Puget Sound, where some tall examples can be seen hanging down many yards out of Douglas firs on some sites.

L. ciliosa is more exciting in flower but leaves do not persist as well (if at all, during winter) and is not as much of an evergreen forest species. But since it is a local native and can be seen growing up conifers here and there it might also work out.

As with other climbing honeysuckles a pile of snaking stems is liable to be produced where the specimen ends up perched on top of a structure.
