Marcelo, Right off, I don't have enough understanding of what kind of architecture conex envisions to have any useful thoughts, but if you are thinking of using HBH options, the effort is certainly faces significant challenges.
But rather than saying "don't use HBH" I'll suggest that you make the case for why HBH is the least worse way of designing conex. Understanding that use of HBH for anything implies serious questions about whether anyone will actually implement/deploy it.
