pissing off all the factions and keeping vertibirds in survival mode. *spoilers*

I recently started a new survival game and have decided to role play as a raider. As i raider i don't care for any of the factions and would rather not have them get in my way as my raider factions conquer the commonwealth. So i want to get rid of all of them. But because it's survival mode i don't want to lose access to vertibirds.

According to the wiki you can do both by either siding with the BoS then betraying them using the minutemen. Again according to the wiki you can side with the BoS to wipe out the other factions directly and then use the minutemen artillery to destroy the prydwen. Once the institute is gone head up to the pyrdwen, stab maxon and steal his fancy coat. This will turn the Brotherhood hostile and should make the minuteman quest "with our powers combined" available. Then just blow up the Hindenburg 2.0, kill the surviving BoS and preston should make vertibirds available and provide free grenades daily in the castle armory.

End result: the surviving random BoS soldiers will be at war with the minutemen keeping them busy instead of keeping settlements safe from my raider palls. the railroad and institute are gone and i get to fly around the commonwealth instead of walking.

obviously i haven't done this myself yet. do you think i'm going to have a problem along the way? it would suck if i blew up the BoS and lost vertibirds. am i missing something important?
