Faster melee weapon speed!

[Omny]

Now that the GECK is out in open beta, is it possible to make melee weapons swing a little faster? Either by default, or by adding new mods to them (cork cores for bats, for example)? I tried tooling around in the GECK myself but it seems that simply selecting "FAST" under the "Melee Speed" drop-down doesn't cut it (the bat still swings at "Slow" speed in-game).
