can I have swiper and counsel as “add-ons” and not the default binding

Question

I like the powers that counsel/ivy/swiper gives me, specially for C-s and C-x C-f, but since installing it, I've started missing the vanilla emacs C-s and C-x C-f. It would be awesome if I can "call" these enhanced versions if I feel lost. For example

To look for something I do vanilla Emacs C-s, and after a few seconds I realize I need swiper, so I should be able to "hop" in to swiper mode.

Likewise, I do vanilla emacs C-x C-f, and after a few tab presses I feel I need counsel(?), so I should be able to to "hop" on to counsel.

Is this a good idea? - Is anybody doing this already? If so how.
