There are multiple different versions of the Fatar keyboards, and my impression is that the PCB’s you bought are not compatible. If there are two contact bubbles per key, then you have a velocity sensitive version of the PCB. Depending on which midi boutique board you get, it may not be able to accept velocity sensitive keying data. Also, your keyboards may not be designed to depress both bubbles on the PCB. Drilling new holes may irreparably damage the PCB. Would it be possible for you to obtain the correct replacement boards?
