What to do with 1200+ of red packs?

[meis]

I've over 1200 of red or medic packs. I didn't use it for ages, obviously. They just sit there and do nothing.
Didn't play friendly matches because I train my players to get 'bonus' in the training ground.

It would be nice if there was a feature where you can convert it into something else, green or blue pack, with a price.

Converting 10 reds into 9 greens/blues.
Converting 50 reds into 46 greens/blues.
Or something like that.
