If you can DVD-rip, you can get the 2-disc original trilogy movies that have both the old and new editions, rip them both and add the new shots on the old movie. It wouldn't be an "official" version, but it'd be exactly what you liked.
The only things I liked were the stuff you mentioned and the new ending for ROTJ. I always hated the Sesame Street song they sang at the end originally, so I much, much, much preferred the more serious music and I liked seeing celebrations across the planets we know, including (at the time) the first ever shots of Coruscant!
I agree with you, most of the changes were neither better or worse, and there were those wretched changes.
Still, though I see why people don't like them, why do so many fans whine and moan and cry betrayal? Just watch the old movies if you don't like the new versions. I guess I don't see why fans want Blu-rays of the original version AND complain when things get updated. Are these changes needed or wanted? No. Does Lucas have the right to change what he wants to with his own work? Yes. Again, just don't watch the newer versions. People can burn their own DVDs or just buy the theatrical DVDs...I have them, so I know they exist.
