I agree that abortion should always be known as a women’s issue and thank you for agreeing that women’s voices should always be centered on women’s issues.
I am a single mom who experienced the terror of unwanted pregnancy, and joy of motherhood. I’m very close to this issue.
I have also thoroughly researched all subtopics related to abortion, such as polls, statistics, studies, the emotional effects of abortion vs. motherhood, etc and I put it together in one big super-detailed factsheet with all my links/videos. I also debunk all the widespread misinformation. If more people were nuanced choices other than full bans vs. abortion until birth, people would vote differently.
This factsheet could give you a lot of the insight that your survey idea would offer…. at least until MAHA accepts your survey idea, that is. 
If you wish to view that detailed abortion factsheet, here is a link to the google doc:
P.S. I also proposed a comprehensive abortion policy, called “Right to Maternal & Fetal Healthcare.” Would you please view it? Here’s the link: Establish a right to maternal & fetal healthcare & stabilize the abortion issue
