There has been an update on this story and it appears to be getting interesting. College Crosse did a story :
Email records show FSU is very interested in adding lacrosse.
"Jennings assured Wilcox that his contact was interested in both men’s and women’s lacrosse"
There is at least potential to add men's soccer and women's lacrosse but some of the alumni were unsure of adding women's lacrosse without the mens programs (it is in the article and I can't just copy the whole thing).
"Also in late May, Fuchs forwarded Wilcox an email that he wrote back on February 23, 2015 in a response to another alum who was interested in Florida State adding men’s soccer. The position at the time was that the school was “tentatively discussing plans to add the sport of women’s lacrosse in the next 4-5 years” and that if the school wanted to add men’s soccer too, that it would need to add at least one additional women’s sport (not counting women’s soccer or women’s lacrosse) to be compliant with Title IX. Fuchs felt that the university could re-engineer the email to substitute men’s soccer with men’s lacrosse to use in their response to the alum that Jennings wrote about back on May 17 of this year."
Of interest is adding women's lacrosse in 4-5 years (e-mail from 2015).
And more info from the e-mail regarding costs and Title IX issues
"Based on our current sport offerings and participation rates, we are obligated to increase our female student-athlete participation rates to comply with Title IX. We are in the process of completing a 5-10 year master facilities plan which will include a proposed facility for the addition of a new women’s sport. At this time, we are tentatively discussing plans to add the sport of women’s lacrosse in the next 4-5 years (approximate start-up & year 1 cost: $6.35 million; approximate recurring annual cost: $1.5 million).
The addition of men’s soccer, based on the average squad size for this sport, would require our athletics department to add one to two additional women’s sports teams (even after adding women’s lacrosse) to offset the increase in male student-athlete participants."
So it seems FSU *might* be starting a women's lacrosse program in the not to distant future. It will be on the short list of possible sports looked at.
