Hello!
I'd say no, morally, if for no other reason.
For what reason would you want to log these hours anyway? To impress employers? I used to be operations postholder for over ten years in the GA industry. This is how it goes: You look at the CV of a jobseeker. You look a the listing of his flying hours. You try to match the two. 500 hours total time. 300 hours aerial work (paradropping, sailplane towing, banner towing, whatever). 300 hours IFR. Dosen't fit together, the guy must be a cheater, the application goes straight into the dustbin. Name goes to the black list. No second chance.
Greetings, Max
