Well, it does make sense to me that baqashos have a level of
personalization that we do not find in shevach. I can insert whatever
baqashos I want to add for birkhas hashanim, so things are more fluid
there.

My question is more your first one -- why must shevach be communal? Not
making up your own adjectives for G-d, I understand; but even if I were
to switch without everyone in the qehillah doing so yet (because of the
lack of announcement), I wouldn't be doing that...

Tir'u baTov!
