Help making a Greatsword wielding Ogryn Hunt Leader

Currently playing Venators and would love to make a crusading style Ogryn with a Greatsword.

Ideally he'd have the sword in one hand and a pistol or other melee weapon in the other.

Current ideas for builds:

Ogryn Hunt Leader

1. GS+susp. and Boltpistol or plasma pistol

2. GS+susp. and Las cutter (expensive but incredible within 1" versatile)

3. GS and Flame or Grav pistol for versatility and cheaper slightly.

open to any other ideas for the Greatsword on an Ogryn Hunt leader as well. Aiming to get the balance between modelling rule of cool and something functional but not oppressive on the tabletop.
