Can I use two runs of 4ga instead of 0ga for big 3?

Definitely need to do the big 3 tomorrow, but I have an issue, I'm already WAYYY over budget on my system. I have a ton of 4ga Monster Cable leftover but no 0/1ga left. Is it possible to run two runs of 4ga "Piggy backed" for the big-3 and get the same benefit of running one run of 0/1??

2 runs of 4ga is equivelent to a single run of 1 ga.
