There’s absolutely no indication of this in the relevant Putnams ‘bible’. Bristol were also asked to submit against the same requirement (15/38 ) but later withdrew – I wonder if their proposal might have resembled their Type 159 bomber mock-up of a slightly earlier date. The FC1 and the Type 159 bear a superficial resemblance, so one could speculate that the FC1 bomber version – if it was ever a glint in the designers eye – would have ended up looking like the Bristol.
