If the 'new' ATR is an addition to the fleet then I could see it maybe going onto the SOU routes to improve SI's product and number of seats vs Flybe which in turn could free up a J32 to operate BOH daily from JER or 4 weekly/3 weekly alternating with GCI. Alternatively the route could stay around 3/4 weekly but on an ATR or even a Daily ATR in the Summer.
So many possibilities! Although I would consider them to be fairly realistic assuming there is space/capacity to do so.
