The timing isn't great. I don't think we have a Supreme Court yet that is ready to overturn Roe.
The danger is that every time you raise the issue and lose, you make it that much more difficult to raise in the future.
Waiting out the retirement of Stevens or Ginsburg would have increased the chances of success.
The Supreme Court tends to nibble away at previous decisions until the original decision can no longer be supported by the more recent "tests" the Court has embraced. This is a full-scale frontal assault on abortion and will be struck down, in my opinion. That won't represent progress. It will further cement abortion as entrenched constitutional law.
Even if Roe was overturned, it'd be a states issus, where is should have been in the first place.
I think the supremes will wait on this as a federal vote. States are issuing their own rules right now, kinda cool. Is it constitutional, fed trumps states....
