Using 2 J15 engines, can you make a plane that goes supersonic in level flight?

Rules and Regulations:
No modded engines (I will check!), other modded parts are allowed.
Minimum speed of 760 mph level at any altitude.
Planes will be tested on high settings.
I really shouldn't have to say this but DON'T TAKE MY EXAMPLE AND REUPLOAD IT! That actually happened last time I did a challenge.
To enter, make a successor of this post or mention me in the comments of another.
Doesn't have to be a new design.

Deadline is March 30th. The person to make the fastest plane wins.
Prizes:
1st place: 10 upvotes
2nd place: 7 upvotes
3rd place: 4 upvotes

BONUS: If you can make a plane that goes supersonic in level flight using only one J15 (not sure if it's even possible), you will get an extra 5 upvotes.
Good luck!

    @Halfstrike 1000 points is a lot of drag, my example has 305 and flies at around 800 mph level

    @Halfstrike Is that the speed of sound? Yeah, for the purposes of having a single number to judge easier, I'll round the acceptable speed down to 760 at any altitude. Gonna put that in the description
