If I told you guns were coming to the next Dark Souls game, at first we'd all think it was awesome, but then we'd all think to ourselves "what the hell are guns doing in a Dark Souls game?". This is just an example but you get my point.
No I'd think "MUTHAFUCKA I BETTER BE ABLE TO BE A DUAL PISTOL WIELDING GUNSLINGER"
Yes, in all caps.
No, But without trying, We would never be innovative and would always be stuck with the basics of 2d Platformers.
WTF are you referencing OP, it sounds like you're talking about a specific instance of something "cool" ruining a game
Also Dark Souls + Guns = Bloodborne and people ate that shit up, its technically not the same universe but I wouldn't bat an eye if blunderbusses and gunpowder pistols that were balanced around Dark Souls' mechanics existed in the world since gunpowder weapons exist in that universe anyway, thats basically what firebombs are
Seems like it'd be fairly easy to balance, as long as it's balanced around reloading versus bows drawing.
And yes, as DotEleven said, I would play it just to dual wield pistols.
