So I understood correctly what you would like to do, but it´s not possible. My last 100% BF of des was done in 34 hours
if input / output data would be right, we can calculate with average of BF time 17 hours
We know that des is 256^7 = 72057594037927936 variations
but 3des is 256^14 = 72057594037927936 x 72057594037927936 = 5,1922968585348276285304963292201e+33 variations
If you want to do BF of 3des on same HW, you need cca 1224979098644774912 hours = 139837796648947 years , so you can forget for this thing friend
