In the scenario that the OP hypothesized, yes, spoofing the fingerprint would help the attacker. A user who attempted to ssh to the router would not be warned that the host had changed and would submit their password to a rogue host.

In answer to the original question, though, spoofing the fingerprint would be extraordinarily difficult.
