Is there a ring flash that fits around the Raynox 'snap-on' style Macro lens?

[John59]

I have a Canon G11 and use the Raynox Macro lens (MSN 202) for photographing snowflakes.

Is there a ring flash that is made to specifically fit the Raynox lens or is it a case of buying one with a large enough internal diameter (something like the Polaroid Macro LED Ring Flash for Canon, model PLMRFC) to go around the Raynox and then coming up with a way to secure it in place?

I bought the Vivitar  LED Macro Ring Flash DR-7000 which has threaded adapter rings 49, 52, 55, 58, 62, 67, 72 and 77mm.

I bought it  for and old G5 and an S5 is. It also came with 4 diffuser rings. So far I am impressed and I cannot afford the Canon Ring flashes.
