Thinking about it now, it looks like some simple Set processing could work, 
without the need to resolve Class<?>s and compare them, because the lists 
in both deobfuscators are already "complete" wrt inheritance hierarchy: 
using A and B ordered sets as input, the resulting list C = (A-B) + (B-A) + 
intersection(A,B), or more simply: C = (A-B) + B.
The idea is that everything that's not already in the list wouldn't change 
the result; this assumes however that the deobfuscators have been created 
from the same interface hierarchies (e.g. if in one case the list were 
C,B,A, where C extends B, and B extends A; and in the other case the list 
were C,A, with C extends A, then constructing a "merged list" B,C,A would 
be wrong; that's really an edge-case and I wouldn't bother if that failed).

Something like:
  LinkedHashSet<String> a_only = new 
LinkedHashSet<String>(d.domainToClientType.get(domain));
  a_only.removeAll(existing.domainToClientType.get(domain));
  ArrayList<String> new_list = new ArrayList<String>(a_only);
  new_list.addAll(existing.domainToClientType.get(domain));
