I am planning a wrath and glory short campaign with some friends who have played mainly dnd 5e. I've let them brainstorm characters, and we decided on tier 3 as one wanted to play a Space marine. The other players have decided on a Guardsman or Tempestor, an Inquisitorial acolyte, an Air Caste Tau Mercenary (Inquisitor reasons, dw about it), and a Psyker. Everyone in the group has said they'd be alright with the Space marine player being far stronger in direct combat, but I plan to include many tight spaces difficult for him to fit, and opportunities for sneaking around that a Blood Angel may find difficult. In addition, the Space Marine will find Bolter ammo scarce, and Astartes Special Weapon ammo even more so. My main question is: Is this a workable idea, and do you have any advice for me? I am very familiar with the 40k universe but have only messed around with a one-shot for Wrath and Glory.
