I can't really imagine Causewayhead or Cornton having the required density to support a station. Cornton in particular -I'm imagining near the level crossing anyway- seems to be largely residential low rises with little (particularly destination) traffic. Though if they can sort out the cycle lane ending south of the level crossing in the process that would be welcome!.
Would a Causewayhead station be on the single line section near the roundabout or further along the line towards Alloa behind, say recycke a bike? I presume that latter would basically be required for road access and car parking. I do wonder how useful the Alloa line is for serving this kind of traffic.
I suppose my main issue is that Stirling, is a city where it is almost never quicker to cycle than drive somewhere, amplified as you go out of it where these station are suggested to be built. There are large out of town style retail outlets and the two roads they propose to have the stations along seem to be two busy roads that can be congested as it is. I say this as someone who has cycled extensively around Stirling council and am, as the OP has alluded to, found myself rather unimpressed with their schemes, even those which I agree in spirit with.
