Regenerate Full Health instead of Individual Bars in Mass Effect 3

I felt quite nostalgic these days and wanted to run a full playthrough from ME1 to ME3, always on Insanity.

But then when I reached the last instalment I remembered how annoying is to always fight with only one bar of health because differently than ME2 we don't have a full health regen, only the most damaged energy bar.

I was looking for a way to tweak that behaviour only in ME3, after all, I've played several times in this 10 years timespan since the first title. It's possible, yes, but even a Husk kills you. >.<

Since usually these settings are configured in the Coalesced.bin I started there, but without much success.

I tried to change the entry SFXGame.SFXModule_damageplayer\healthregenpct (that's how ME3 Coalesced Utility shows to me) from 0.25f to 1.0, 1.0f and 100, repacking the file and restarting the game after each change, but the health doesn't regenerate as expected.

I didn't want to download one of those mega tweak packs form Nexus to not risk making my playthrough super-difficult (or super-easy). It's just this single píece of "immersion" if you call it that, that I don't really like.

Anything else I have to do?
