Can I create a 2nd child theme in bp-scholar?

Hello there,

I've just installed and tweaked the files for the bp-scholar-child theme, and I was wondering if it is possible to create a 2nd child theme?

I really only want the 2nd child to be very slight changes to the css (backgrounds etc) of the first child.

Is this possible? any thoughts to help a newbie through?

Thanks in advance
