OK, not sure what the 'yes' was in response to, but I should perhaps note that you probably need to choose between the Bohmian theory or the transactional picture, because they are mutually exclusive. There are no 'beables' in TI. But there is a clear solution to the measurement problem and no discontinuity between the relativistic and non-relativistic domains as there are in the Bohmian theory (which has to abandon particles as beables at the relativistic level).
This last statement is not correct. Bohmian theory can now be applied to the Dirac particle. You do not have to abandon the particle for Fermions at the relativistic level. There is a natural progression from Schrödinger → Pauli → Dirac. See Hiley and Callaghan, Clifford Algebras and the Dirac-Bohm Quantum Hamilton-Jacobi Equation. {em Foundations of Physics}, {f 42} (2012) 192-208.
