The case law on this is really strong and the answer is no. Registration (cleverly) is not considered punishment, so there is not an equal protection argument. Our courts have deemed registration a regulatory issue, so it does not open up the Pandora's Box that you are suggesting may be proper.
While I am not opposed to 290 registration, and I appreciate its purpose, I also appreciate your question.
I can cite a bunch of cases on this issue, but you can also find them discussed in article on my website. This is a complex area of the law.
Sounds like the change specifically excludes 290 registrants. The change allows an early application, that's it, so before the previous 10 year period.
