If he had guts he would employ the same degree of analysis to Jedi and the other Raiders sequels.
If Lucas really wanted to do special editions why not get someone to look at the dodgy effects work in TOD or TLC (only heavens please let Spielberg and Paramount insist on treating them the same way as his ET special edition).
On second thoughts lets hope Ady or someone of his elk* give them and KOTC a go.
