AS I was playing Lotro (before 2014) I was using this:
https://www.lotrointerface.com/downl...inManager.html
Not sure if it still works. Or maybe it was replaced by the ingame plugin manager now.
But there never was something like Minion and I doubt that Minion will ever support this.
Maybe if Minion get's open source and some devs have the need to support it, but this would also need the lotrointerface website crew to support it then.
You should ask the lotrointerface crew for waysx to achieve this FIRST as Minion will ONLY download if the database and data is accessible from their websites.
Minion alone got no data and will never have it.
