Harry & Ginny, magic from Vmort? (some ship)

There was some discussion in Chamber of Secrets whether Harry's 
skills (parselmouth) came from Valdemort and now Vmort has Harry's 
blood in him.

Ginny was similarly marked by Tom Riddle's diary (Did she speak 
parselmouth to get in the Chamber?) Ginny was in the background for 
the last two books but there was some hinting that she's friends with 
Neville and Hermione. How about she quietly gets top marks at final 
exams in Goblet of Fire and starts wondering whether her magic is 
hers or comes from Voldemort?

A subplot for the 5th book might be Vmort tempting both Harry and 
Ginny that their powers come from him? Would they stop fighting? 
Would they lean on each other without the giggling hero worship of C 
of S? Any thoughts?
