Don't know if you have seen it but Tim Miller already showed interest in her for a sequel

We will have to see I guess. Obviously I would very happy about that but I will also not set myself up for disappointment.
There was already discussion here and there about which actress could play her though. This article suggested a few names for example.

Tatiana Malsany doesn't sound bad actually.Orphan Black funnily enough has some similarities with Lauras backstory and she definitely has the looks for it.
There is of course an argument to be made about how old Laura should be. Tatiana Malsany for example is already 30. I personally have no problems if Laura would be around 20 in the movies because she isn't a stereotypical teenager anyway and appears older just by her personality so it really doesn't make any difference if she is 16 or 20 IMO.
Now as for if she would work in an R-rated setting. Well the likes of X-Force, Target X and Innocence Lost answer that with a big YES
