The answer is yes, because the basic geometry of both airplanes is very similar. As the wings are swept, the CG moves aft, but the center of lift moves aft much more, thus more stable. And more importantly, huge down loads on the tails to trim, which means more lift required from wings/fuselage and of course more drag. How huge? It's been about 50 years since I worked with F-111, and many of the specific numbers have fled my brain cells, but one number stands out. Tail load in a 7.33g turn at high mach number was 50,000 lb down on each tail.
Wow blimey so actually increased tail downloads!
