Lionel milk platform and fastrack

Hello, I am interested in one of the lionel milk car operating accessories. I have an automatic decoupler installed. However, I have elevated the ground surrounding the track to near the level of the ties. I presume the platform would need to be trimmed. Could someone who has one tell me if that seems within the realm of possibility? Thanks!

Just install a tradition tubular track section or 2 where the platform will go. Menards has transition pieces
