Alternate wire sizing
 
If 1/0 THHN is rated at 150 amps @75 degrees and #4 THHN is rated at 85 amps. Can I runs 2 strands of #4 in place of 1 length of 1/0. Technically it would handle even more amps than 1/0. It's a short run.

Not code compliant.

Wires need to be larger than 1/0 before they can be paralleled.
