Convert EB3 to EB2 ...is it possible ?

A colleague and I were talking about how slow the retrogression for I-485 is progressing and he brought up a point about how EB2 category priority date is moving much faster than EB3, currently Jan 2003 as opposed to May 2001 for EB3.

So we were wondering if we could convert our EB3 filing to EB2 because the requirement for filing in the EB2 category is that you should have a work experience of at least 5 years.
At this point I do have 6 years experience.

But after doing a little more research, our hopes were destroyed :)

Here is the Murthy forums post that talks about it.

So we have no choice but to wait for our EB3 Priority Date to become current...bummer !
