Leylandii hedging which has been cut back hard into the brown wood is , IMHO, one of the ugliest sights I've ever seen in a garden (or elsewhere for that matter)... If you have a soul (and I think you do ) my guess is that you will regret it.
Ive seen many attempts to camouflage it - none successful.
I would either cut it down and replace it with something beautiful and wildlife friendly, or find a way to keep it trimmed regularly and keep it as a formal backdrop to what sounds like a lovely border.
