The way to run one bike is to just ride all the awesome AM trails.
Get invited to Whistler for a park day? Decline the offer then go ride the valley trails.
Get invited to Pemby to shuttle? Decline the offer and pedal up Nimby to Middle Earth.
Just sever off riding with the guys that only ride DH bikes.
If you only ride with a group that are always on AM missions then it's easy. Gets harder when you start craving a park day of shredding. Sure DH tires and putting a coil on will make it more enjoyable, but you won't be hanging with a group that are hammering it on full DH bikes.
All comes down to self control.
If it's an experiment, to see if a Big Bike guy can survive and be happy in the AM bike world that's a whole other story.
