Do as you want, dual lone wolf is the easy win option, on tactician and even more on normal.
You can try a 2h warfare/necro, a 2h/poly (focus on strenght, some points in memory as you unlock interesting spells, and the rest in wits)
Summoning is good on anything really. But I prefer using summoning as a support spec or full on spec, if you use it on your ranger he will lose a lot of fire power (and you will maybe waste points in memory for summon spells, instead of just putting more points in finesse).
And with LW, cap points is 20 : you will have your big fat champion incarnate at 10, but 20 is the max you will get (you need this cap obviously if you want to go pure summoner).
