chances are pretty good that one Warré isn't going to cause problems for the existing native pollinators. if you were to bring in a whole bunch of hives, that could very well upset the current balance, but one shouldn't be a problem.
consider what might be the factors limiting pollinator populations. they need nesting sites, nectar, pollen, and
water. honey bees won't have a noticeable impact on nesting sites or water. depending on what the mix of plant species in the area is, they could compete somewhat for nectar and pollen, but again, one hive isn't going to upset things terribly.
also, I'm sort of surprised that there aren't honey bees there already. you don't say where your cabin is located, but there have been honey bees in Minnesota for quite some time now, and I would imagine that feral colonies are distributed fairly well across the region.
