Yes/no? Parallel conductor termination

Without going into the reasons why or why not, here is the scenario.

Install parallel conductors (8 per phase) for voltage drop when 4 per phase will handle the actual amperage just fine. The breaker terminations will only accept 4 per phase.

Solution, terminate 2 each of the 8 conductors on a power terminal block then come off of that terminal block to the breaker with 1 conductor. You would need to do this 4 times per phase. This way you have the 8 conductors between source and load, but your final termination into the breaker will be with just 4 conductors.

Electrically, I see nothing wrong with this. Anyone have a code reference that might prohibit it?
 
Generally speaking, voltage drop issues are not a code requirement.
There are other considerations you need to deal with, such as 310.4, 310.16, parts of Art 240 (overcurrent protection), 110.14, etc... If you comply with these sections and any I did not post, I do not see any issues.
