A couple of combo's I like that I haven't seen in this thread:
Ippon seionage -> kouchi gari
Harai goshi -> Osoto gari
We drilled kosoto gari to tai otoshi a couple days ago. It seemed surprisingly effective. Assuming standard grip and right side kosoto, when you go in for it a natural defence is for them to step/hop to your left to get away from the reap. When they do that they've created the space for tai otoshi: plant your reaping foot, turn and step back with your left, shoot the right out low and tai otoshi.

One of the ways into it that I came up with for getting to this was off a Ko Soto. Worked quite well.
Great post. I likle the physics of a lot of your combinations. I can play them out in my head easily.
Personally I think ren raku waza is a bit over rated. Before people freak out, you need to look at why you're doing it. The primary reason to use it is to move your opponent into a specific position to be able to do the main technique you are setting up. I find that sometimes people focus too much on using set up techniques to do this rather than using gripping and kuzushi which are more efficient and effective.
In higher level judo my experience is that combinations are definately used but not in so much of a choreographed way. They tend to happen spontaneously as your opponent reacts to your intial attack (which has the intent to throw). Obviously there will be some more typical reactions that happen fairly consistantly and on that basis you're going to start using that combination. Spontaneously you will come up with combinations that happen on the fly and often without really thinking about them. You will simply see or feel an opening for one of your primary throws and do it without having planned it as you entered into the initial technique.
Using grips and kuzushi is generally safer than using an attack to set up your opponent since you can't be countered as easily. The danger with using combinations is that it takes the emphasis off of using your gripping to set up your techniques. As well you get reliant on them. In my case I can't do yoko-tomo-nage without using ko-soto to set it up.
I guess my main point is not to get hung up on using combos. Let them happen spontaneously and drill them from there. Look at what situation you're trying to create and see if you can create it with simple gripping and pulling instead.
That said, typical combos I use:
Ko-uchi -> Yoko-tomo-nage
Drop Ippon-Seoi -> Ko-ouchi (while grabbing the ankle)
Uchi-mata -> Ankle pick
