If the paladin also has paeon and is spamming flatbades in the between all that stuff it's very doable. alot of people forget hallowed ground is more than just oh shit invincible button it has a fairly decent chunk of emnity attached to it.
Personally if I've built tp outside on the mites then I typically run in flash / voke, fast blade flat blade and once everyones around around and hitting miser use rampart. Then fast blade, flat blade aegis, sentinel your spirits within, then flash, voke, dv, sp, cure etc hit your hallowed ground hopefully in time with the second round of howling fists and you should be pretty much golden.
