Veg plot project

Right all, I've been out measuring my leylandii hedges, the short one on the west is just under 6m with the biggest gap between trees is 170cm. There are 3 leylandii after this length which are behind the shed which I'm planning on removing to give an angled entrance between the end and the shed.
The long side to the south is 21m and is made of 26 leylandii trees. They are in a pretty straight line. What are peoples thoughts on removing the branches etc from the leylandii to leave just the trunks (to whatever height we choose) and using feather edge boards horizontally between them to form a fence. Alternatively should I build a frame and attach fence panels? I am planning on doing both sides to make the fence decorative from both sides.

Someone who lives close to me has bought a house with two large Laeylandi in the garden. Instead of taking them out to add more light to garden they have cut off all the lower branches up to about  8 foot high and created 'Lollipop' tress. It actually looks quite decent!
