Demoman Detpack/Voice Addition

For detpacks, you're able to grab a new pack off a fallen demoman. Was thinking two ideas;

1) Maybe a way to after a certain time, generate these with the engineers dispenser... say after 2 minutes of it being up n running and/or if an engineer/demoman throw their ammo bag in the disp. that includes a detpack(means the engineer would have to grab one from an a fallen demoman- maybe wrench the bag a time or two for it to be usable...)

Even more, when there is a detpack available in the dispenser, maybe an added model rises from the top of the dispenser that shows that there's one in there to grab.

2) When an enemy demoman dies with an unused detpack, in addition to dropping a bag, maybe add a new model showing a detpack wiring harness or something that looks a little different from a set detpack but similar.

Maybe also add a voice to the demoman 3 seconds before the detpack goes off saying something like "Get away! It's gonna blow!" or "It's about to get messy" or "Watch out, Incoming destruction" heh

Thoughts?
