One observation I have is that you could include one free stopover in the ticket. So, in theory, you should be able to book PEK->SFO (stopover)->MCI (destination)->SFO (maybe an overnight connection)->PEK as a single award ticket for 65k plus taxes.

I ran some quick searches and could find availability around your dates for 97,500 miles + $41.50 taxes each. (Shockingly, the SFO->MCI segment is the problematic one. You might just want to book the PEK->SFO->PEK at 65k.)

Do you have any miles in any programs right now?

Instead of HNL, what about San Diego (SAN) ? Much quicker trip. You could purchase tickets outright for under $200/each right now - might get even cheaper.
