No.
Encryption with HS is end-to-end in any case. 
Eve cannot reroute data to fake HS without knowledge of onion identity private key.

Active (Mallory) attacker can drop or modulate circuits stream without decryption.

Worse attack scenario: obtain a copy of identity private keys >50% DA --
Directory Authority nodes
(undercover operations, installing bugs, TEMPEST, etc) and 
full emulate connection with fake consensus to
virtual Tor network through DPI on ISP-level
and decrypt all the traffic on the fly.
