First, you should color match the two video, and align them spatially and temporally; then, you must measure the exact rectangles used by the logo - I'd use three, two for the writings, and one for the AMC logo - and their spatial position; after that, you should replace those rectangles with the ones taken from the good source as "patches"!
Isn't not that hard - after you spent a LOT of nights testing the technique... 
I use avisynth, but I think it could be possible to do that also with Premiere...

I beg to differ  . Just kidding but the spatial aligning is something I've struggled with. Thanks again Andrea for the advice.

Ok so an update. Taking some advice from Doombot, I was researching how to do rotoscope in Adobe Effects to fix the hole under Bishop when I had an idea. I thought about Adobe Premiere and using layers and opacity. So I re-graded the HDTV broadcast to match the BD. I then layered them up. I turned down the opacity so I could match the frames spacial as much as possible, kind of in keeping with Andrea's advice. The HDTV broadcast is 1.77 vs the 1.85 of the BD, so the HDTV has more top and bottom picture whereas the BD had more info on the right (the HDTV was a little more stretched and wrapped too).
So once lined them up, I got the HDTV broadcast and carved out the area where the logo was and lowered the opacity to 0 so the lower layer of the BD came through. And it worked as long as the color regrade. This was the simplest fix since the area of the logo is in the same place all the time. Problem was I noticed all the imperfections of the HDTV broadcast. Not as sharp, lower bitrate, etc. So I decided to reverse the procedure and have the BD as the top layer and bleed in the HDTV part. Problem is unlike the logo, the area to cut keeps changing. So basically it was like old-school manual rotoscoping, I cut the scene into each frame and manually craved out the area to add the HDTV part.
It worked pretty well. Only problem was the HDTV was still a bit pixealted, so Doombot re-grained the HDTV for me, I did the process again and it seems to be a pretty good match:

I even found a mistake in the BD footage. When the computer guy painted out the hole in the ground he didn't fix the lens flare in one frame. You can see in this pic the triangle cut out of the blue lens flare under Bishop's armpit:

Yes nice! I'm holding up rewatching the film until you release the TV cut with all the nice Blu-ray quality and revisited colors (just please don't make it like the old HDTV pink master lol)

Thanks Stamper. I'm not sure how long the work will take so you might want to watch Aliens now if you got the itch to. My plan is to stick with the 95 LD's colors for now. There are a lot of pluses and minuses about that transfer but to me it seems closest to what a theatrical print would look like. Plus it goes with my Alien regrade which also uses its 95 LD.
Is it the correct transfer? No most likely not but out of all the transfers I can find its unique in not being pink, overly bright and lifeless. OR totally green like the BD. And if you like Cameron use of blue, this transfer is ultra blue. I think it will be 95 LD TV cut then theatrical and then I will finish up my 35mm trailer version. Kind of off of the DVD colors for now but you never know.
Anyway if you like the second pics over the first pics, this is the project for you, if not maybe a future one...
BD/BD regraded to 95 LD

Just my two cents: now that I see those pictures, I remember that the laserdisc colors are almost always "pushed" to be colorful enough for the ancient CRT TV sets... just try to set the saturation at 75%, and let me know what do you think about the results...

Good advice. Here is what it would look like at 75%

The blues are still very prominent but it does look more balanced.

I like the early ones, but they are indeed a bit pushed. Could you try a middle point like 80% instead of 75%?
