So I'm thinking of running a Blood Angels list with Assault Terminators and attached Sanguinary Priest in Terminator Armor. This means there must be a model converted to be in Terminator Armor but only wielding a Power Sword (with Chalice). No Stormbolter. Here's my first prototype:
That's an Assault on Black Reach Terminator with his Stormbolter traded out for a Grey Knight Terminator Nemesis Force Sword. I'm not too fond of the AoBR model quality, so I may end up getting a box of regular Terminators to do the final model. The Power Fist in this case would be explained away as decorative. Another option I was considering is to use a Terminator Sgt Power Sword and cutting the Stormbolter off of a hand.
