I would have that fairly far down the list. Not at all to say they won't work on it. They should and they will.
You are bringing two immense talents together. Your top priority should be to develop your pairs skills, starting from stroking and tracking right through to lifts and twists. You want them to be seen sooner than later as a real team. As far as elements go, the twist is the most important element in pairs IMHO. More than any other element, the quality of your twist can slot you internationally. You want to make solid progress on that early.
Second is to find your 'secret sauce' - something that's going to get the judges' attention and, will in turn, cascade a positive halo onto the other marks. For them, it might be lifts or unique and appealing packaging. Some early exploration there would be in order.
If I'm a betting man, I will say Richard downplays the importance of the sbs jumps. They are important but no more than a death spiral or pairs spin. You want to put your skaters' mindset in a more positive frame of showcasing their strengths to build marks rather than obsessing over weaknesses. You do that by making it to them just one of many elements.
Particularly in the last year with Dylan, her jumps became the focus to the point of almost dysfunctional training habits. The result - she got worse and worse. He, in turn, became noticeably more distracted and started to miss as well. Reverse psychology is likely their more promising path.
