It would be simpler to set up Jenkins if the bitbucket-push-and-pull-request-plugin could support ssh keys to propagate the build status to bitbucket
As mentioned by @cdelmonte-zg in #108 , There is a limit while propagating the build status to bitbucket, propagation will work only if you are using, for the git plugin, credentials of the kind: "Username with Password".

I will research for other options, I just mention this as a "nice to have" feature.
