There has been a newly discovered exploit in which you can unlock both trophies with ease very quickly, see ‘Hardcore’ for more information. Also go for the bad ending here as well so as to avoid a potential 3rd playthrough since you won’t be attempting side missions in order to save your crew members anyway.

Another important thing to note is that you CANNOT change difficulty using chapter select, so cleaning up trophies on a Ranger Hardcore run would be problematic, it’s vital that you cleanup most if not all misc trophies before moving on. Use chapter select to cleanup any chapter specific trophies and whatever else before starting a new game as this won’t allow you to use chapter select. This may not be necessary, all trophies that require a set number of kills, cleaning your weapons and such all carry over to new playthroughs and chapter select on the same save slot.
