As I dug deeper into this I realised that the forum post format no longer suffices to properly document the remakes, so I switched to spreadsheets. I also combined my findings with non-DOS remakes and clones which I found earlier, so the list is pretty big (but still far away from exhaustive):

You can sort the list by any column by adding temporary filters (because I'm sharing this in view mode). By default it's sorted by platform so all DOS remakes are in one place.
After some pondering I decided not to use any labels, such as "conversion", "remake" or "clone", but rely on descriptive parameters, some of which are also inaccurate ("recreation" is really vague), but at least they do not force any particular game to be shoved into one single definition.
Note that there are probably some inaccuracies here and there. I took and extra mile to specify license type for both remake engine and game data, following the example from Libregamewiki, but in some cases it's not easy determine the game data license.
I'll be happy to get any feedback and/or criticisms you guys might offer.
