Pretty late answer i'm guessing but you can do this with the colourspace ofx plugin. The problem with that one though is that it is built to convert from one colourspace to another in a mathematically precise way which is not always as aesthetically pleasing like it would be if with a DRT. For example you might convert from logc to rec709 and find that the highlights are clilpped and look awful. The data is still there and you can recover them but it's not as pleasing of a conversion as the arri lut that resolve is supplied with.
