And then everyone fell crippled to acute radiation poisoning and no one could pull the lever.
Yeah, after I wrote it I thought: "Man, this would be so much riskier to attackers unless they do it really-really well".
It sounds like a fun idea to explore in the setting but realistically it'd be a nightmare.

I figured we would be starting around the 12th century, with guns being a mild rarity and the production of more advanced guns being a lost art.
What separates early-mid medieval ages from late medieval ages can be often narrowed down to guns and metallurgy.
Actually, metallurgical developments weren't even new that big since other cultures had blast furnances prior. Guns and chemistry are a similar deal or the idea of military drills.
We have random pieces lying around which people can use as inspiration. I think it does make sense if people catch up with them.
Not saying we'd go beyond the medieval setting but for example seeing a modern gun would put the idea in people to make their medieval weapons shaped more like that. Which is strangely means in a certain aspect that leads to hundreds of years of leap in gun development (firearms took a "gun-like shape" by the 16th century). Mechanism of a modern gun can also help people inventing mechanical locks for guns earlier.
With 12th century developments things are still rather crude in quality but the above for example still aid them to create better tools.
Also it'd lead them to make plate armors and more decent quality metal products early.
Those are just my thoughts on the matter.
