I like your idea, but what game are you talking about? I am the worlds worst tinkerer with such things and love to get my fingers into as many pies as I can.
I like the Vulcan for what it does not how it looks, which is shoddy and half baked. Just look at the kinks in the leading edge for W's sake.
The BICh-26 on the other hand is a beauty! But it is a terribly flawed design, which is why it was never built. Look at all the other weirdo designs the Reds built, but they did not build that in spite of all the conferred advantages!
Low aspect ratio wings have tremendous advantages when it comes to speed, low wing loading and ability to pull very high AoAs. But they suffer in sustained maneuver, range and cruise speed. The three reasons why it was never built.
You see, all aircraft are trade offs. And the designer trades away stuff that is less important to get stuff that is considered more important.
