It is basic geometry that your peep will be further away from your eye it you keep your standard form. How well you can see your sight through it depends upon your eyesight and the size of the peep verses the size of the sight and the distance between the these two.

The other problem with this situation is that standard form and anchor may have to be altered. This depends on the archer and how comfortable he/she is with their present form. It is many times too uncomfortable for longer draw archers with short ATA bows.

The other problematic issue is that there is more possibility to cant the bow.
