Indeed. Adam Murdoch coded up something very similar in the Myrmidon proposal, 
I think. From memory, this development allowed a classloader to be made up of 
an aggregation of delegate classloaders, instead of requiring a simple tree 
of classloaders (where common stuff must be in a common ancestor). This way, 
2 classloaders that need classes in common could share a classloader that 
loaded those classes, without needing to load those classes in a common 
ancestor. (I'm sure Adam can explain it all a lot better than I).

Might be worth having a look at the code - even if it's just for ideas.
