So basically this is kind of software OoO at assembler level...

This is useless for pure 68000 as AFAIK it does not have instruction scheduling issues -- and other cpus of the family don't have many of them anyway.
Also needs to be specific for 020-030/040/060 for which sheduling is different.
There must be complicated hazard detection to avoid false positives (= cases where the instructions can't be swapped without changing the behavior).
Presence of labels is of course to be taken into account (an instruction can hardly be moved at the other side of a label without changing behavior).
And as already said, it is useless for code that's not time critical (= most of it).

At the end, while in theory possible this would be a lot of work for very little benefit...
