The inseam is actually 32", not 35", and when you sit down these move up quite a bit due to the knee armor, so they might come close to fitting you without taking them up.
But to answer your question - depending on how well "refined" of a hem you're looking for, it could be easy. I've attached a photo of the hem of the ones I received.
