Most of this question is driven solely by money.

6v turn signals for my bike are expensive, relatively, $60 a corner. 12v are free, I already have two sets of stock ‘looking’ 12v LED’s.

not wanting to switch the entire bike over to 12v, tried that once and I find it hard to get all that smoke back into the wires once you let it escape.

i have a pair 6v to 12v converters already and 12v LED flasher units. So zero $ spent so far. If I had not had all the 12v parts I would not ask this question but I am being cheap, at least while my wife is watching. 😎

From what I understand on the bike there is a black and grey wire going to the stock flasher unit, black (6v power) in and grey out to the switch.

the 6v to 12v converter is power and ground in, power and ground out. So my basic wiring mentality would bring the 6v black (power) wire into the converter and the 12v power wire out into the 12v flasher relay, grounding both ground wires on the converter. The 12v grey wire from the relay then goes to the switch, then to the 12v turn signals. The turn signal light on the gauge cluster would also need to be changed to 12v. Which I also have on hand.

is it that simple or am I missing something?
 
The only thing that stands out to me is that you give me the impression that you view the ground on the converter as separate from the ground on the rest of the circuit. I think it should share the common ground for the full circuit.

Shouldn't you only need one converter and one flasher relay?
