I have been thinking on this.
For any pick up game the unit will likely be used as a Dakkajet, or it is best to do so.
The only time it will be used as something else is for a very casual game, where having odd units is entertaining and encouraged. Those games will include only those players who really wont get anal about whether the model is properly representative.
There should therefore be no issue. The shortcuts will only make the bommers 'confusing', only for casual games with lists designed for fun I would try out a bommer. Players who like to agree to field armies based around 'fun' units wont get anal over the model, and will accepta bommer as what I say it is just so long as they can see the underwing bombs and the turret.
The Dakkajet used in open play will be equipped exactly according to
WYSIWYG, with six front guns, no turret or bombs, so nobody should therefore have any problems with it even a 'That Guy' looking for an excuse for a whine.
Problem solved, Methinks I will glue on the wing guns and magnetise the underwing stores. It will look brutal and have much simplified swaps.
Thank you for the reply.
