Sarah Kane - Crave, possible?

For my drama piece in college my group and I are thinking about doing Crave, by Sarah Kane

I don't know much about it yet as I've only briefly seen the script, but do you think it would be possible to interpret it in a way to be performed by 3 girls?

We only have to do about 15-20 minutes worth, so not the whole thing, and we can incorporate other people's lines to other characters or I suppose, given the nature of the play, miss out characters all together

Any advice would be appreciated, I think the general assumption is that two of the characters are boys, but do you think it could be done?

Thank you
