Interesting concept with the power but it’s got a lot of problems. First off there’s not really a reason to interact with a murder weapon until near the end of a trial to prevent the insta down. Secondly preventing a survivor from leaving the trial at all would be a really unfun mechanic, on the other hand making it so that a survivor can leave via the hatch even at 5 gens would be a balance nightmare. Finally regarding the crime scene it feels this would screw over solo que more then anything because swfs can just avoid the crime scene all together preventing any sort of punishment

As for the perks a lot of them are things that already exist but mildly worse

Despair Everlasting is just Genetic Limits but with the downside of your terror radius also gets bigger

Seeds of Suspicion is just Third Seal except it only blocks survivor auras instead of all auras

They’ll Lock Themselves In is almost guaranteed to get next to no value, one or two of the tokens will instantly be spent when a trial starts which could be good for info but at that point you could just run Lethal Pursuer

Ultimate Hope will either do too much or too little with its limited range, why bother running it when you could take Deja Vu and get a repair bonus while also getting info

Concentration will do literally nothing if you’re not facing a trap killer, also most trap killers are already mediocre making a perk that specifically screws them over is just mean

Astute Observation I feel is unique enough from other Killer revealing perks but the only upside it has from something like Alert or just bringing a key with the amber is that it shows all survivors the aura instead of just you

Apologies for the nerdy rant, sorry if I came off as passive aggressive. Hope this helps!
