I'm a member of the FreeSCI team. There are indeed plans for turning FreeSCI into a ScummVM module. This is a lot of work though, so it will be a while before you'll see this module in a ScummVM release. At the moment, it would be best to port FreeSCI if you want an SCI interpreter on Pandora.
I should point out that support for newer SCI games in FreeSCI is still ongoing. KQ5 and Longbow do run, but cannot be beaten yet, while other games like KQ6 do not run at all.
