I wouldnt give bolters to the DC, since you have Lemartes. You lose 5 attacks with WS/Str 5 with reroll to hit and to wound (from Lemartes) and you gain 5 shots with BS/Str 4. Not really worth it imo. Generally i dont like JPs on the DC, due to their cost, but unfortunately its the only way to include Lemartes, i know. If you really want Lemmy in, keep it like that, otherwise i would suggest to Pod them(you already have a Podded Dread for first round so it seems good). Mephiston is a monster indeed, but still i think that the original list with the Priest and only one Tactical can work well enough.
