Yes, you'll have to make an additional skin with the name "skinname_fpls" (no head with body) or "skinname_fpls2" (arms and saber only) for every skin you want to use in True View.
I'm not sure yet but I may only make support for _fpls because there's no real point for removing the body when that's part of the appeal of doing True View. AND it would just add to the workload for skinners/modellers.
