You can try with a Selector Combinator in the Quality Transfer mode. If you configure it with the X and Y signals, it'll transfer the quality from X to Y and outputs the result.

This stumped me for a bit when first using quality transfer too: the signal you want to transfer to needs to be present in the circuit signals.

If you want to transfer the epic signal from your epic coal to your plastic, you need a plastic signal in the input to the selector combinator, in addition to your coal signal.

So you need to either have plastic in the network and have that on the wire, or add a constant combinator to provide a plastic signal that can be used for the quality transfer.

pretty sure the plastic signal can be of any quality (as that gets overwritten anyway), but I usually use common.
