The only issue I can see is who on earth would want to play the poachers.
You could run it as a map based campaign where players ran competing anti-poachers units hoping to win the big contract (or the lion's share of the defense budget if gov/t forces) from Country X.
They could plan patrols/surveillance ops and ambushes and devise a random(ish) encounter based on their activities. Each activity could cost resources/lead to different encounters. When an encounter occurs for a group, the owner/CEO/Colonel running the group plays his guys and the other player plays the crap bags (and would have incentive to harm/cost his competition as much as possible).
I guess alternatively you could figure out an AI for the crap bags. Roll and encounter as a movement to contact, player ambushes or player being ambushed and use something like 2 Hour Wargames to run the poachers based on the encounter type.
