Too much soy, imo. Especially a cupful.
Only 1 tsp won't be noticed if added or skipped.

Here'a tip for adding things and not knowing how much
to add. I do this when mixing custom paint colors.

Pour 1/2 of your sauce in a bowl and save the other half.
Add just 1 TBS soy sauce, stir it up then taste it.
Need more? add 1 more TBS, stir then taste.
Keep going as necessary but keep track of what you add.

Once you get to a taste you like, just add same amount
to the other half then combine.
If you go too far, you have the original to bring it back
to what you liked.

Substituting thigh meat for the breast meat sounds good.
Also 4-5 hours on high sounds like overkill to me.
I would probably start with one hour on high, then
turn it down to low for an hour or so.

Hope this gives you some idea help.
Just my $2 worth.
