All are possible at least in theory; the question is of how easy they are to do. A lot of these will require a good sit down to get going.
The easiest is the invincible chain patch:
This however causes Keen's shots to still hit it. (And the Tank's too I believe.) There is a patch to stop THAT but it then stops the Chain blocking, killing or freezing Keen.
The next easiest patch is the block-freeze-kill one. You'll have to pick one:
Once that is done it may be possible to combine that with a 'shots pass through' patch. This too is easy but can't be done until you make your choice. (For one thing it will affect the Chain patches above for... reasons.)
After that, we'll see.

For riding butler bots, in KeenDroid I used lemm's ice cube platform patch and then applied that sprite value to the butler bot. But the side effect is that ice cubes are no longer useable as such (though maybe you change their property to a tank bot bullet or something?)

Ah, yes. This is the other part of that patch:

a freezing chain is the most interesting if it makes keen slide left or right.
causes the chain to block without pushing, instead of freezing.

Ok, so this is what I have so far. TAKE NOTE; these patches all work together; they override ALL the patches above so you must DELETE THEM from your patchfile or they will sit around making trouble. (Just want to be clear on that. If you get a problem like 'The game crashes when I touch an ice cube!' it will probably be because you left old patches in.)
This covers nearly everything you want. The Chain cannot be destroyed. On contact it freezes Keen like an Icecube. Icecubes also freeze Keen.
While frozen Keen has God mode. When not frozen he doesn't. This does interfere with the cheat but if you want a cheat exception things get Lemm-level tricky. When frozen Keen hits a wall he unfreezes. He is still immortal while unfreezing.
Keen can ride on the Butler Robots but not the Tank Robots. The Butler Bots push sideways too, like moving Platforms in Keen 3.
These patches won't work with the original graphics of Keen 1. How do you want the Chain to work? I'm assuming it just bounces back and forth off of walls, it doesn't need a turning animation. Will it animate at all?
The Butler Robots can be made to fly through the air too.

Once again this overrides all the above patches. (You will notice it's mostly the same as the above anyway.) The Chain falls and moves back and forth without animating. It also walks off of edges. This causes problems for me as the Chain freezes Keen and pushes him along, keeping him frozen forever. You may want the Chain to fly like a platform so Keen can be frozen then fall down out of the way. To do this replace $E8 $08F0W in the last section with $90 $90 $90.
The speeds of the Chain are $005AW (Right) and $FFC4W (left) Change these to speed or slow it.
I think this is everything. It leaves a lot of patch space open for more fancy stuff.
