I grow a couple of hebes......salicifolia.....that are some 10' tall. I prune after flowering and do this by cutting back to lowest new shoots. you can cut older stems but only if to buds.
i would also take cuttings....quite easy....and replace. If you want a 2 or 3' shrub you can buy smaller varieties that are almost that height. Buy a replacement now and you will,have something nice in that space for this season. ,make sure you replenish your soil well
