Wouldn't this cause disconnects due to misbehavior?

A standard node connecting to a relay node would receive
blocks/transactions that are not valid in some way and then disconnect.

Have you looked though the official client to find what things are
considered signs that a peer is hostile?  I assume things like double
spending checks count as misbehavior and can't be quickly checked by a
relay node.

Maybe another bit could be assigned in the services field as "relay".  This
means that the node doesn't do any checking.

Connects to relay nodes could be command line/config file only.  Peers
wouldn't connect to them.
