Why not expand the shadow to standard, so you can use
Keening Wail? Without support you're not likely to get initiative during your shadow, Nertea won't live to see the regroup and with Toldea they will just exert a companion.
I would go standard, some more enduring nazguls and than go with
keening wail, witchking and his pale blade, you'll have some fun
.
Fellowship is cool, I gues you won't be seeing much conditions and events this way
. Oh and in expanded you play on the 'new' sites, so Prancing Pony to grab Gorn I guess....
