Definitely try and make friends with the neighbours and get them to cut it to a more socially acceptable 2 metre high.
You could then erect trellis panels in front of it and grow a wide range of climbing or rambling roses, clematis, honeysuckle,
Failing that you could try covering the ugly stuff with clematis which will cling and climb but you'll need more than one and they'll need to be vigorous so have a look at the montanas. You could also try Virginia creeper which will give fabulous autumn colour. You could also try a really large rambling rose such as Kiftsgate, Rambling rector or Wedding Day if you can tie them in and up.
Whatever you plant will need very good soil preparation as the conifers will suck all the goodness and moisture out of the soil so prepare deep holes and back fill with a mix of garden soil and good quality compost plus some slow release fertiliser such as blood, fish and bone or pelleted chicken manure. Sprinkle some mycrorhizal fungi on the roots of your new plants to help them grow well and water in well at planting time and until established.
Clematis benefit from being planted several inches deeper than they were in their pot and roses need to have the graft union buried an inch or two below soil level. Feed them with specialist fertiliser every spring to keep them healthy and vigorous.
