Direct fire table using a D12 ?

[davep]

Hi guys, nice to be here. I’m collecting PG games, I have yet to even punch one though, let alone play. BUT, after watching numerous play throughs on youtube, I had one thought regarding the outcome of combat. Has anyone tried using one D12 instead of two D6 for direct fire? The odds of getting a 1 or a 12 are so much greater. I really like the game as is, but I think I want to see some more bloodshed. Anyone use this house rule? Can you see any unseen side effects. Thanks
