You could, I suppose.............but the cost would be more than the cables and it would void the warranty so I wouldn't do that. If you have an issue later you will want to have the warranty intact. Hope that proves helpful here, even though it wasn't what you really hoped to hear. Please get back to me again if you feel more discussion here would be helpful as all follow ups are included in our fee.
Having never done that on these models, I can't say and I doubt any of us here have due to them being models we rarely see here. I think you might have to contact a local RV dealer over there or Dometic directly for that. I will opt out of this and let another tech offer something on this if they can.
