IMHO you should consider one of these:
a) What is the matter of your order?  To have uniform appearance of
locale expressions?  In that case, you might consider specification of
parameters by *name*.  See the Isar reference manual for the syntactic
b) If you really want to have structural control, consider grouping your
parameters to records.  HOL-Algebra is a nice example how this is
accomplished in practice.

Hope this helps,
