I have done it with the new Peco bullhead as follows. Remove the inner half of the Peco chair about one in 3 sleepers. Thread C&L chairs along a length of bullhead rail to sleeper spacing (aprox) A little of the chair needs removing to get the guage set correctly.
The problem then cane in fixing the chairs to the sleepers. Mek didn't work, or Plas Weld, or super glue. But I found a new style stuff in the hardware shop consists of a drop of glue where the chair goes, followed by shining a blue light from the accompanying torch for about 5 seconds. Seems to work well.
Sorry, only photo I have showing it.
