I read it again but didn't think it worthy of a pedantic reply to the effect that the positive g loading during the entry must be less than 1, reducing to 0.5 at the 60 degree bank, then instantaniously increasing to 2g during the turn.
Re-reading your description, I would suggest raising the nose slighty just before you introduce the bank. This should be a fluid motion and you should be using full aileron for the roll.
The aircraft is not required to maintain this attitude. The turn MUST start as soon as you reach the required bank angle.
