Probably, yes. When it comes to encoding this, I'm gonna need some advice by some more knowledgeable members here to make sure everything is as it should be to be compatible.
My recommendation is that for the MKV, break compatibility for the sake of quality and compression efficiency. That is, except for software encoders. Go for 16 refs, 16 bframes, any other specialized non-compatible good setting x264 has, etc. This will break the decoding compatibility for pretty much everything except software encoders on a PC, but it will improve the quality and bitrate efficiency by a significant amount. I also recommend ditching the 2pass bitrate for the more advanced CRF setting, which produces unpredictable filesizes because it analyses the video and gives it the bitrate it needs for the specified value.
If people need hardware compatibility (DXVA etc) then they can get the AVCHD and play it on their PC, no? :)
Anyways, I know my way around x264 pretty well so I can probably help with any compression questions you may have. I also recommend ditching any encoding GUI and going for frequently updated commandline builds which in addition to being more frequently updated also give you full control of what settings to mess with and tune. I use JEEB's custom build @ x264.fushizen.eu
Also, since you're going to be using MKV, you could include fun stuff like soft subtitles of the original English version for multiple languages, multiple language tracks in a more effective compressed format like OGG or AAC (=good quality+not much space taken up), and a lossless FLAC encoded audio file of the 2.0 Laserdisc mix that's used as the basis for the 70mm recreations. I also think you should softsub the Greedo subtitles unless you're making them look very specific. But even then, .ass/ssa subs (+Aegisub editor) have a lot of features and allow you to use various fonts and move the subtitles around the frame on a per-line basis, etc. I do anime stuff so that's why I know a lot about encoding, subs, and containers. :D
Unrelated question but for the 2.0, are you still using recompressed sources (HDTV/BD rips etc) or untouched sources (BDMVs, HDTV transport streams, and such) ? I haven't been keeping up with 2.0 much unfortunately. :(
