I know you're just joking. But Spielberg will not allow Lucas to muck with RAIDERS. In fact, he wasn't happy that ILM digitally removed the reflection of the cobra behind the safety glass in the infamous Well of Souls shot, but he did let that fly and kept it in. Lucas also had ILM produce an alternate digital shot of the nazi car going off the cliff during the desert truck chase. Spielberg nixed it immediately and kept the aging bluescreen model shot. So, I'd say there's no need to worry about significant RAIDERS alterations as long as Spielberg walks the Earth. And Ford would probably break Lucas' kneecaps, too.
