Is there anything to suggest that she was?
The closest thing I found is Saoirse Ronan saying
“Yeah, I did [audition for Star Wars Episode VII]… I don’t know whether I should have said that now! I mean, everyone did. Everyone has auditioned for it. So many people I know have gone in for the part I’ve gone in for, and guys who’ve gone in for a particular part, so I’d imagine J.J. is probably just scanning the earth to find the people that he needs.” - empireonline.com
It doesn't sound like she was seriously considered though, supposedly the three other names that stand out were Elizabeth Olsen, Jennifer Lawrence and Shailene Woodley as non-picks.
Elizabeth Olsen, Jennifer Lawrence and Shailene Woodley were considered for the role of Rey, which went to Daisy Ridley. Olsen refused the audition because she had a contract with Marvel Studios for the role of Scarlet Witch in the Avengers’ franchise and because the shoot dates for The Force Awakens clashed with Age of Ultron. In April 2014, J.J. Abrams chose Ridley as Rey. - news.com.au
Casting for Rogue One didn't start until Spring of 2015
Back in the spring of 2015, even fresh off the acclaim for "The Theory of Everything," there was no certainty that Jones would be the one cavorting with Stormtroopers. Equally established actors Rooney Mara and Tatiana Maslany were also reportedly circling the part.
Edwards now admits he was prepared to enlist Jones from the very beginning. It didn't hurt that they grew up just a few miles apart in the British Midlands and shared a similar sense of humor. - nydailynews.com
So I'll say no.
With two different directors, each one had their own idea what they were looking for. JJ was looking for Daisy Ridley, and Edwards wanted Felicity Jones.
