Was the Amplexus an early Stigmatisation?

St. Francis of Assisi and St. Catherine of Siena are two saints famous for having received the stigmata, that is the wounds of the Crucified Christ on their own bodies. That was a subject much-desired in the High Middle Ages. But is it possible that St. Bernard's (legendary) amplexus was a stop along the iconographic road that led to the stigmata? Consider the following images of Francis and and then, a modern image of Bernard, whose legendary reception of the Crucified's embrace would have pre-dated Francis.

Note that Giotto does not draw a specific connection between Christ's wounds and Francis's.

This miniature model is currently on display at the OFM house in Salzburg. The connections to the wounds are quite precise.

This is Clemens Maria Fuchs (21st c.) showing the amplexus.
