Indicator to shift chart

A 4 hour chart will bars starting at 00:00, 04:00, 08:00, 12:00, 16:00, 20:00.

Is it possible to shift these over 2 hours so the 4 hour bars actually start at 02:00, 06:00, 10:00, 14:00, 18:00, 22:00.

I know this can be achieved by using a different broker but I wondered if it could be done with an indicator or script.

Yeah it definitely can. Probaly not easy though. I heard if it's shifted 2 hours, the data is much more cleaner. I know my coder has an indicator that shows candlesticks in a chart window, so I know it's possible.
