I'm pretty sure you can do the same thing with expand-region and smartparens combined and is more general than manipulating sexp.

There's also evil-lisp-state (which is essentially a modal interface to smartparens), https://github.com/syl20bnr/evil-lisp-state, and evil-smartparens (https://github.com/expez/evil-smartparens) which makes the default motion operators work better with sexps.
