As you have discovered, the two features are incompatible.
An alternative would be to "roll your own" mail merge by creating a template
in which you insert {DOCVARIABLE} fields in place of {MERGEFIELDS}, then use
vba to iterate through the records in your datasource creating a new
document for each record and setting the values of the document variables to
the information contained in each record and then updating the fields in the
document. That can be done with the template protected for forms.

This is not going to happen as Form Fields are being deprecated in the next
version of Word.

And being replaced by what? Seems to be MS hasn't actually improved the
feature set of Word since version 2 became version 6.
