I have absolutely no idea what will happen on console sine I have never done console development.
The main problem would be the refection code in the Blox DLLs. Even if you export scripts these DLLs are still present and can't be removed since the scripts depends on types declared in the, The exported scripts are not stand-alone.
But on console the Mono runtime should be used so it would be similar to making an Android or WebGL build. The Windows Mobile is an issue cause there a special cut down version of .Net is used which removes some things that Blox needs (and if I could test properly I could probably support it by just using what is available in that version of .Net).
