Per-shot colorspaces are generally handeled by the OCIOLooks not OCIOColorspace. Additionally, with Looks you are able to use conditionals (atleast on unix, Id have to try it on other systems) 

So if you had a Look called "perShot" with a file transform pointing to /path/to/$SHOW/$SHOT.lut  you can then apply the Look using a conditional like "perShot|" where if perShot fails it will do the pipe/OR and instead do nothing. You can even do more complicated combinations like "+look1|+look1+look2|". 

This is pretty specific to Looks that modify the view, but that's usually how shot-specific transforms are used. You might be able to use this for other purposes if that isnt your use case.

Thanks Kevin, seems like it would work.

However (if I'm not misunderstanding) this would require all shot luts to be named the same and also be in separate directories? In my case I would prefer to have the luts named shot01.cube, shot02.cube etc and store them in the same directory (i.e /show/luts/shot_luts/).

I guess I can just create a dummy lut if it doesn't exist as a pre launch process.

Create a null lut is about the best you can do, combined with the search path you could do

search_path: path/to/${SHOT}:path/to/null

then use a name like "mylut.cube" if you squint hard you can make this do sequence level as well as show wide level, by suitable nesting of directories in search paths.
