Bigger sized jackets?

[Argentcroix]

I know it has been brought up before, but not with any finality that I can find. Does anyone know of a semi-dry top or good paddling jacket that will fit a 56" chest and still allow for some layering? I have tried on all the xxl gear that the local stores have, and no joy. I have been told that they don't make em larger, and that the one maker that did (extrasport) is only making pfd's now. If there are none to be found, do any of the manufacturers do customs? Or are there other options to add to a pair of stocking foot waders to be dry warm and Safe? I appreciate the help!
