I am also not telling the potential password, I can just describe, what language I used, names symbols etc. , all this information could be very helpful to bruteforce it.
I also could provide original email from when I bought the ether, but this doesn't proof much, as it also could be stolen.
I know this is an old post, but somehow it slipped my attention, and i've just seen this now.
Have you ever considered a forensic examination of that PC you used whenever you had access to the wallet?
And have this password ever been used anywhere else?
I know chances of finding anything now if the PC has been used since 2016 would be very slim...
