Why not build up an Allison QEC too and then it could be flown with any of the three! Merlin powered for training future Buchon pilots, Allison powered for giving rides and general airshow appearances, and the DB for those really special occasions!
Very nice idea. Though I am not in the know I´d think the attaching points for the Allison might be different ones than either for the DB or the Merlin. My personal guess is, they just wanted to get her airborne reliably and fast, so they went for the Merlin option. (I read somewhere they had low oil pressure issues during the previous (3 ?) DB testflights) I´d think the Allison conversion wasn´t finished / proven at that time. But anyway, will it be worth the effort to have a 3 different engine QEC system? Was it ever done? Though there was a 2 different engine QEC system intended for the Ta 152, changing between the Jumo 213 series and the DB 603 series (everything firewall forward, complete engine, oil cooler and cowlings (neccessary due to right / left hand charger).
