If your addon adds /follow <charname> and /assist <charname> support (it doesnt work by default) then it would be possible to do proper FTL using the Mapped Key Wizard's new "Text Entry" option.

Use the Mapped Key Wizard and set up a new Text Entry mapping under Non-combat, and set the text to send to "/follow {CHARACTER}", send Enter after, and set the Target to Window:All w/o Current. Same for Assist, just use /assist {CHARACTER}. This would give you fully working FTL.
