No. I also don't think that Semantic is well suited for that.

As for highlighting, there's already the semantic-decorate minor mode
which will highlight the semantical expressions found in the
buffer. When activating it, you'll already see that Semantic doesn't
parse the contents of functions, for example. It only parses (parts of)
the contents when you're within that function, to determine the
variables/types/etc. in the local scope.

Regarding indentation: this is much more a matter of taste than
semantics or syntax. If there was a direct connection between semantical
analysis and indentation, why were all those wars fought for the
"correct" indentation of C, for instance? Just looking at c-style-alist
will make that clear. There's also a very good write-up regarding this
issue from Steve Yegge when he dealt with indentation of Javascript:
