I'm not fully up on which carriers Aeroplan collects YQ for. I'd assumed TK and CA were on the list, but if they're not, then there might be some creative options. Looks like the two stopovers (ICN and BCN, with PEK as destination) are allowed only if there's no open jaw, so it would require the same trick as DL (routing back to SFO) but could be done as a single award. Here's the list of YQ/non-YQ partners for Aeroplan.

All that said, OP doesn't have enough points that can be transferred to Aeroplan to make such a trip happen, since there are only 30K MR points. Perhaps via a foray into coupon connection, however, something might be arranged. Looks like Aeroplan would only want 125K in J for the mini-RTW, which beats the 170K DL + UA/UR combo that's been posited.
