So, the thing that Fight! puts in the game is that you can’t always get what you want. Sometimes there isn’t a “Get the Orb out of the Keep” option, most often because you said “I want to steal the Orb” and then either failed the test or got handed a high-Ob test for a skill you don’t have and decided to fight instead.
When you change that, you make it so that any outcome in the game becomes negotiable using weapons. That’s a very, very substantial change: for one thing, it means you can escalate from the DoW to a fight without giving up the stakes. For another, it means you can force a conflict (I can refuse a DoW, just totally refuse to negotiate because my daughter ain’t marrying you, no way, nohow, and I don’t care what you say about it. I can’t refuse to get stabbed. If you can stab me into agreement, that’s a major big deal).
“But wait!” you say. “I only meant for, you know, physical outcomes to be Fight-able!” Okay. Why do you need a Spark for that? By RAW, your example is totally achievable. The guards will want to script a lot of Locks to grab the PC, then they’ll put him in jail. The PC will script Withdraws and Avoids.
So: Is there a class of outcomes you consider appropriate stakes for Fights that are not currently achievable in combat?
Also: there’s a problem where the side effects of Fight! (wounds and hesitation) could interfere with statements of purpose. Like, let’s say my SoP is to get the Orb out of the Keep, right? Yours is to murder my ass right here and now. We fight, and it’s rough, it’s really bad. I win, but in the same action you incapacitate me. What happens? Apparently the sight of my blood arouses such pity that you sneak me out of the castle and get me to a doctor?
This is a major problem, because you can’t just say “Don’t write SoPs that can’t be fulfilled if you’re wounded” (You can just as easily take a Mortal Wound on the last round, and if you’re ruling out SoPs that require a live PC… that’s pretty much any physically-realistic Fight SoP, leaving only ones like “I beat you so hard your daughter agrees to marry me” or “I beat you so hard that unicorns are real.”)
On the other hand, you can say “Fine, incapacitation or death mean you lose, no matter the dispo.” That mostly works, but there’s still a broad class of sensible SoPs that don’t make sense if you’re really badly hurt (especially if the other guy is unharmed). If I’m fighting the Life Guards outside the throne room, and I “beat” them on dispo without scratching them but they beat the shit out of me, to the tune of -4d and a superficial… How exactly do I then climb the wall (my B3 Climb skill is unusable due to wounds), swim the moat, and get back to town unseen? And what exactly happened to the guards? I mean, at the end of the Fight they were armed and unharmed and standing within swords’ reach of me, but then something happened? Yeah, sometimes this is explainable because I ran away or whatever, but if I haven’t been scripting Withdraw or at the very least Maintaining while they failed to Close, then what’s been happening in the Fight! must be different from what’s actually been happening? Or something?
