I'd say it's not possible. Aside from the fact that a called #macro always
expects the same number of params specified in the original, there is a
problem of ambiquity. Let's say, out of 5 parameters the 3rd isn't
necessary. How would you go about omitting it?
The best I've managed was to have long parameters (strings or vectors) take
the value 0 as an alternative meaning "do not use". This, of course, is not
always applicable for vectors. Another thing is to make it possible to use,
for example, "3" instead of "<3,3,3>" by manually promoting the float to a
vector (#local Vector=Float+<0,0,0>;)
But what you want, I think is impossible.
