The entry height is not a problem; the entry speed needs to be appropriate for the entry height. 350 KIAS is a very safe minimum entry speed for a loop entered at flypast minima (30 ft for some pilots) with 0 flap and will give you an apex height of in excess of 5000 ft albeit, as you say, needing full T7 thrust.
