The F124 is bigger, over 4 1/2ft longer, heavier & twice as powerful So it is doable, especially for carrier use. I enlarged the nacelles in my blank to accomodate a larger engine, I did consider the BR700 but found the specs made it far, far to big to use.
Try as I might I haven't found another engine to compare with the Larzac that is in production as I am trying to keep it semi-RWish
