[Click] Passing a element declaration to an elementclass as parameter

[Cliff Frey]

Not directly possible.

The closest that you can do is either using some other macro language (i.e.
the c preprocessor), or making a 2-input, 2-output elementclass, where you
do

my_eltclass [1] -> CONFIG_STUFF_GOES_HERE -> [1] my_eltclass;
