Wrapping Templated C++-functions and embedding Julia-functions subject to templates

I’m looking into the idea of treating instructions as data for an C++ Eigen-algorithm.
I already assume that the g+±compiler will be able to resolve the wrapping to Julia using
Cxxwrap: GitHub - JuliaInterop/CxxWrap.jl: Package to make C++ libraries available in Julia

The number of functions implemented on the C+±side will vary with the C++ main-executable implementations. Is it possible to (‘dynamically’) wrap the Eigen-dependent Julia-implementation back to C++?
