I doubt it; I've never seen anything like that. The problem is, your need for a high reliability component that has a low manufacturing sales volume pretty much translates into $$$$. I wouldn't expect that to change till Jandy, Hayward or Pentair come out with some system that depends on such a part, transforming it in a high sales volume component.
I will point out that infloor vacuum systems are HUGE energy wasters, because they require such a high volume of high pressure flow. You might be able to set up a timer to put your pump on HIGH and simultaneously open flow to the vacuum. That approach would have the benefit of using available parts AND saving on electrical operating costs.
