The method I described previously should work.  You place one patch (membrane + 
embedded protein) at some location within a large box using editconf -center, 
then combine with any other system(s) that have similarly been positioned using 
editconf -center.  The tutorial I linked before demonstrates a trivial example 
of something similar, but it illustrates the logic behind the process.  You 
won't get any clashes to be automatically resolved/molecules deleted, but even 
with small gaps or unequilibrated boundaries, a gentle equilibration protocol 
should resolve those issues.
