Quite possibly, but it's not my area of expertise—far from it. In the U.S., there is ICE, the organization that takes the kinds of individuals you're describing—individuals who have tried to get into the country several times, who have committed a serious crime—and immediately puts them in prison. There is no prevaricating on that.
But if you're considering a policy, you have to define what you mean by a high-risk immigration case. If, let's say, you have a good definition of it and it's empirically supported, then electronic monitoring might be quite possible.
