The chief engineer in Naracourte SA did a conversion. Sliced some of the wings off and put a kero burner in the front. Might be worth giving them a call, interesting project.
Have you considered about over-stressing the a/c with that sort of power in the front especially in summer when there is only really a good three hours in the day where it is not rough as guts at survey height? Kind of pointless if you are running it at half power most of the time. Data is not going to look that good either if you are screaming over peaks at around 200kts.
