I routinely boost in to the station through the slot, inbound and outbound. Works fine, rarely have a scan actually finalise.
My typical method is to line the station up in supercruise, end supercruise then immediately boost engines, request docking, boost again and that gets me pretty much right at the stations cage you fly through to enter. If no scan so far I just stroll in, if scan started whilst boosting in, I line up and boost in to the station. Immediately cut engine power, rotate ship 180 degrees as I float through the station and hit 100% throttle once pointed back towards the front of the station. Great fun, never hit anything.
I mis aligned my boost outbound once and boosted directly in to the side of the space station just above the slot from close range in my Python, lost all shields and 40% hull. Can't imagine the refugees gave me a good customer satisfaction score upon disembarking.
This heat sink idea of popping heat sinks. Your talking about when silent running yeah? You can just rock up with all systems on, not in silent running, and pop heat sinks if a scan arises can you?
