Mabipale can be updated with send support, since it's open sourced and uses the Alissa API.
That's dwarfed, however, by the following:
- MabiPale is a packet logger. Unlike AA and other "tools", Pale isn't designed with sending in mind. By the time you implemented send support, and the required user interfaces for it, in Pale, you could have just used AA and been done with it.
- MabiPale with send support still requires a packet source capable of send injection. The only such packet source is pake + mod_alissa. Morrighain, Pale's de facto source, does not and never will support send injection. And honestly, it'd be easier and more rewarding to fix pake than to try to add it to Morrighan.
