mididings has already been suggested. It has a somewhat steep learning
curve, but it'll convert any MIDI event (almost) any way you like.
To simply swap controller number and value, run this in a shell:

mididings "Ctrl(EVENT_VALUE, EVENT_PARAM)"

One of many ways to do that:

CtrlFilter(range(63, 128)) % (
    Chain(CtrlMap(n, n-62) for n in range(63, 128))
