Hacking burner's firmware to enable DVD overburning

Hi everybody!

I’m trying to figure out if it’s possible to hack the firmware of a burner in order to enable DVD overburning. Particularly, I’m referring to the slim IDE DVD writers coming with laptops about 10 years ago (Pioneer DVR-K17A, in my case, but I could get other second-hand models of other brands, if necessary). I’ve known that the majority of burners doesn’t support DVD overburning. But this operation just concerns the writing beyond a certain number of sectors.
So, if the firmware contains a limit of sectors beyond which the burner cannot write, what about finding and raising that limit in the firmware file?
Is that possible, theoretically?
