This isn't going to help you much, but if memory serves, the clutch slave cylinder isn't hard to remove. At least from the few times I've bled the slave cylinder, the way and angle it was attached it's not hard to get a set of wrenches up there.

Both look straight forward, but I've not had to remove either on any of my BMWs prior so take THAT with a grain of salt.
