If you are a vendor and saved a copy of the timelocked transactions it might be possible to get Bcash from Hansa and Bitcoin Gold from Traderoute multisig escrow addresses, not just the bitcoins that were stuck.
I'm not sure about the exact process yet, nor if it's indeed possible but here are some links:

Guy who runs a service to get BCH and BTG out of multisig addresses might be able to help for a fee /u/walleting_services/
Please let us know if someone succeeded.
Yes just open the hansa timelock xslx file without any precaution
