No, it's not a reasonable fear. I've done this many times without problem. (But you can't do silly
things like de-allocate the super block. LVM makes it easy to get right but probably not impossible
to get wrong.)
Sounds like tune2fs options will do what you want though maybe they don't scale. I think you'd want
a special purpose file system to tune, not /.

That's what virtualization is for and it's a better use of your time.
