It will be illegal to release them anywhere but your own yard and your neighbors may have some thoughts about that and you will probably have some regrets as well.Theres always the chance you can find good homes for them but odds are thats would only be a few. How many eggs are there?
Odds are they wont hatch, but they might. You can do a google search for "egg candling" which will tell you how to look for signs off life. If she were hit by a care or someone/something attacked her to kill , chances are the eggs are damaged and not viable.
You will possibly get some negative feedback, but actually from people that love iguanas. Their plight in Florida is hard to watch but most of us understand not everyone wants 20 iguanas crapping in their pool. :)
I am curious about this scenario, so do come back with updates. If they hatch it will be nothing short of a miracle
