1/2 time midi temposync?

[elephantgrey]

I am thinking of replacing my eventide time factors with a chase bliss tonal recall, but the TR doesn't do dotted 1/4 notes (crotchets​), only dotted 1/8 notes (quavers). I use dotted 1/4 alot on my TF, but am still GASimg for the TR​. It's also smaller, so I would be able to get a reverb on my main board.
Is there a way I could 1/2 the midi tempo going g into the pedal? I don't really use super short delays anyway.
Preferably I'd like something that 1/2s the TRS midi so I don't have to have 2 empress midibox's. Or even would it be possible for someone to mod a midibox's so one output is 1/2the tempo?
