I was just thinking that the the bad mixes might on average fill in the gaps to what the processor actually had for resources.

Even GPUs, which have arguably far more predictable instruction mixes, struggled massively to get a useful utilization on VLIW architectures – AMD tried two different ones from 2006 to 2011 before they finally gave up on the concept and started using RISC architectures like Nvidia had been using all the time.
I'm not sure I see how MT would solve the mix problem, if each thread gets an issue cycle (and each thread itself has a bad mix).
