Going off your supposition as a hypothetical, I suppose there's an arguable possibility of, say, having Benefic/II put a Synastry buff on the target to make future heals transfer to them for a period... but then your immediate next cast of the same would just overwrite it and swap the target anyway.
And that's before you get to balancing it against Synastry's 2 min CD, which would be more trouble than it's worth to reproduce without the button.
You'd probably be better off just cutting Synastry and the beacon aspect entirely (an effect which is hardly ever used anyway...), and just putting a "Neutral Sect Cure Potency" addendum (or other CD, though the only other 2m CD currently in our possession is Divination) on the Benefic spells for the extra potency lost.
The major failing of Synastry in AST's kit, however, is that the job has relatively little reliance on its single-target GCDs for healing, which is why the effect is underwhelming in our kit. Compare this to WHM, for instance, whose healing arsenal is weighted heavily towards its GCD heals (Lilies, Plenary Indulgence, etc), or to SGE who could simply tack it onto the existing effect of Kardia or Soteria to add some flat cure potency to its healing spells and address its lack of panic-healing options. It simply fits better elsewhere, and AST's kit doesn't have much room for it anyway (even being muddled as a "unique gimmick" option on a job made of much more distinctive gimmicks).
