6 BGV+ancient and chaplain, and 6 ICC with azrael

Trying to justify buying the target Dawn of War box. Not knowledgeable enough on tabletop to really know if these 2 units will fit in the same list without eating into each others roles. Wondering if this would be casually viable especially in 1000pt game, since im pretty new to tabletop.

Thinking was BGV on the center objective(take and hold) as a killy enough unit with staying power. ICC to harass elites, maybe disrupt opponents secondary objectives. Would run with 3 eradicators+gravis captain, 5 hellblasters, 10 scouts (5 man squads),
