Well, the Dwarves did have at least six (possibly in suspicious Elvish eyes seven) rings that they accepted from Sauron, and that was, presumably, after the fall of Eregion when 'Annatar' had revealed himself.
But we do get told that there were some Dwarves on the side of Sauron in the War of the Last Alliance:
"All living things were divided in that day, and some of every kind, even of beasts and birds, were found in either host, save the Elves only. They alone were undivided and followed Gil-galad. Of the Dwarves few fought upon either side; but the kindred of Durin of Moria fought against Sauron." (Silmarillion: Of the Rings of Power and the Third Age). I think there are also a few other bits here and there.
So there is a possible scenario of a Thranduil who had faced Dwarves serving Sauron in battle there that is supported by canon, I think. One could make something of that.
There's the bit where Gimli says that Thranduil's halls were built partly with Dwarvish help, but it is possible that was before Dagorlad, I suppose.
