How about a wall trained shrub rather than a climber as these will not attache themselves to the wall at all, you will have to tie them to the supports, and I would suggest using horizontal wire between vine eyes as the best solution.

Garrya elliptica (silk tassel bush) has wonderful silky tassels in winter when not a lot else is about, and grey-green evergreen (or evergrey-green!) oval leaves and is not too vigorous unlike the thorny pyracantha.
