There are plenty of disarm kits - leave it as it is - failure needs consequence - no need to carry 50 but there is certainly enough
The "consequences" here are just cumbersome rather than real consequences though. Just get rid of the item entirely, or make it a "tool" that you only need one of and need proficiency to use. If you fail, you set off the trap. If people want to save scum that, they can save scum the current setup anyway, but at least for everybody else it would be a straightforward system that doesn't encourage silly packrat behavior.
