IFR or VFR is not relavant.


Separation requirements make the crowding-onto-the-runway exercise
unnecessary if both flights are IFR, as the local controller would have
plenty of time to taxi the second IFR guy onto the runway before the
second flight could be released anyway.

You need 3000 feet between two single engine aircraft for your runway
separation and then 15 degrees divergence for your IFR separation.
