It is possible but from what i tested it is quite hard to make other mobs vs mac tusk aggro one another so i would not recommend trying - unless you have like 1x20 stack of killer bees that you could just drop at his proximity and run away. I tried mac tusk vs tallbirds and while they by some miracle did attack each other tallbirds are quite dangerous as well, especially if your plan would go the wrong way.
If you ask me... Man up, get football helm, wood armor and ice staff plus heal up to 100% before the engagement. Carry with you some decent healing and perhaps some tooth traps to deploy prior to agro'ing the dogs and just kill them and then him. Ignore wee mac tusk, he is worthless. And ther you go - shouldnt be too hard asuming you wont make some terrible mistake like using near depleted armor/helm/staff.
Questions? :D
