According to someone who says that they worked for Hasbro some time ago, there were some really early plans to redo Deluxe Universe Cyclonus toy as Triggerhappy (with new head), and Deluxe Universe Galvatron as Gen2 Megatron (with new head).

These ideas didn't get beyond the first stage of a mere concept drawing of the new heads superimposed over a photo of the toy, so don't expect there to be any lost moulds out there.
This is more just a "what if" that might tease a few fans out there.
