Nice choice! But from the looks of it....they don't appear to be durable.
I think something more along these lines (see link below) might take more wear and tear....but will they fit...that's the question??? If you have the time I would just take the dimensions of the roadster luggage set / luggage compartment and drive over to a retailer and see what they have...especially for that price.

Funny, all this time I've had my car and I haven't tried fitting luggage in there.
Good luck with that.
