afigfan,
If you have in mind to use two or three sources of wasps at hand, say capable of providing pollinating insects during the months of June and/or July, you could go for ,as you suggested, some cuttings of appropriate varieties of dedicated caprifigs.
With all respect for other opinions, I do not think the edible caprifig could effectively do the job.
I say -two or three sources of wasps- because from experience, Caprifigs are very vulnerable to climatic change as well as some yet undefined genetic behaviors which may determine a failure to have sufficient Profichis in time....if one fails you still have at least one or two stdby's.
I think UCD could provide the necessary support to identify the best varieties for you. Starting from cuttings it may take at least 3 or 4 years for your young trees to generate good caprifigs and they have to be adequately caprificated when with some receptive figs.
Ideally you could buy rooted plants if available.
Nurseries here sell potted caprifigs of various types, year round.
But, as I see it from the distance, my first priority if I were into your shoes, would be to locate the tree from where those wasps came from for that visit to your backyard...May be it is there waiting for you, and an air-layer or two could solve your problem rather quickly.
you could possibly have a couple of good potted pollinators in your backyard a year from now !
