Personally I don't understand why you would want Lone Wolf. Considering AP is the most precious thing in combat and with LF you potentially half your available AP every turn, so for me the benefits doesn't compensate at all for the loss. But everyone got their own play style.
As for your question, I haven't completed the game so I really can't answer your question but I would take a guess that it would be viable. I personally would try to get MaA quickly up to 5 to increase the effectiveness of Thick Skin and also get the Weather the Storm talent.
