Perhaps by using a targetfilter?  e.g. assuming the role definition 
entry is cn=MyRole,ou=people,dc=example,dc=com
dn: ou=people,dc=example,dc=com
...
aci: (targetattr="uid || 
cn")(targetfilter="(nsRole=cn=MyRole,ou=people,dc=example,dc=com)")(version 
3.0; acl "Allow people to see other role members"; allow (read, search, 
compare) roledn = "ldap:///cn=MyRole,ou=people,dc=example,dc=com";;)

This allows people who are a member of MyRole to see the attributes uid 
and cn in any entry under ou=people which matches nsRole=cn=myRole,.... 
(i.e. any entry which belongs to that role).

I haven't tried it out but this or something like this should work.
