We already have a very simple way to express such things:

   (curry (lambda (x2 x3 x1 x4) (f x1 x2 x3 x4) arg2 arg3)

this also has the advangtage that it is naturally extends to

   (curry (lambda (x23 x1 x4) (f x1 x23 x23 x4) arg23)

and many other cases we can't even think of yet.
And it requires ZERO extra C code.
