If I wanted to do this I would call up the tower with a taxi request to re-position the aircraft elsewhere on the airport, and if that can be arranged to cross a runway…
Would it make a difference from asking to taxi to the active for a VFR departure? After all ATC is neither in charge of crew licensing or air crew rosters.
Would it be normal for one of these to fly VFR?
No. All ifr.
The potential perpetrator might be better off to stick with different types, intended for VFR operations at smaller airports

I suppose not, but is not being normal cause enough to be denied takeoff clearance?
