Yep! I recommended that it this post:Another way to balance Con would be to replace death saves with Con ability checks. So sure, you can dump Con and it doesn't matter much, until suddenly it does.
I love this idea but it'd never happen.or,
remove CON and paste it's mechanics to STR.
I absolutely like this approach due to a slight front load on survivability at 1st level.I've been thinking about going back to 4E style Con. No Con to HP per level, but add Con score to HP at first level and add Con mod to HP healed per hit die. So high con will give you a little more hp to start (your meat), and it will help you recover faster (your endurance), but your class and level will determine the bulk of your hp.
My favorite thing about HP in 4th edition was I actually saw lower Con characters. Players didn't feel like they had to boost their con all the time. In 5th, I tend to see Com 14 all the time. At least 12.
While we're on it, I think Survival should be tied to CON by default.

Is it? There are games with attributes other than D&D's that get along just fine and don't have the sort of problems you are predicting here. It's likely that if Gygax had used only four or five attributes, people would be arguing in favor of those instead of the hegemonic six.Terrible idea. Every Wizard now looks like Hulk... Also wrestling poison and diseases down is a bit problematic. You can be healthy and weak or vice versa.
Do you roll or average on lvlup?Due to the abstract nature of HP (skill, luck, endurance, favor of the gods, etc.) we house-ruled for a while that you can add your highest ability score modifier to your HP when you level, not just CON.
But, since then our desire to remove HP bloat from the game, you add your highest ability score modifier ONCE (at level 1) and then just gain HD when you level (no ability bonus). If your highest ability score modifier increases (likely), your HP also increase by the same amount.
It works well IMO, but to simplify things even further, we now just award +5 HP at level one (since nearly every PC gets a +5 ability modifier somewhere eventually), getting max HP at level 1 for your HD, and then only HD after level one.
So, the "rule" we use is. You do not add your CON modifier to HP. You gain +5 HP at level one and that's it.
This would work nicely, too.
