As I mentioned above, this isn’t something we support at the moment. We only support GBP / BACS direct debit with GoCardless. But your feature request is the right way to go so we can monitor interest in this request.
The thread was merged with the existing feature request which you linked to, so all the votes are merged together and in one place - Support other currencies and collection schemes in GoCardless - #11 by QFMathew
