Could We Get an "Anti Alaising" Pass for Progressive 3DL Rendering?

...I have been using the progressive mode for 3DL.  For one, I like the fact it lets you see the entire scene much more quickly, particularly during test rendering, so issues in he scene can be caught early without having to wait for the process to finish.  Second, when using IBL Master there are certain situations which cause unwanted render artefacts in standard (bucket) mode that do not appear in progressive mode.  Unfortunately progressive mode only does four passes and at times if an item in the scene is shiny (not necessarily reflective) the highlights will have jagged edges which is a sign of poor anti aliasing. 

Is there any way a fifth anti aliasing pass (similar to Bryce) could be added to the process in the next update to eliminate this?
