The F-14 has been kitted by several manufacturers. Yellow Aircraft & DCU are a couple that come to mind. There is a very large one being kitted in Germany (for twin turbines) and Jet Hanger Hobbies does a small electric one. You can also get F-14 plans designed by Philip Avonds in Belgium.

There was a British Tornado kitted at one time but I don't remember who kitted it.
The B-1 has not been kitted, to my knowledge. There have been recurring rumors of a possible kit in the future.
BTW... F-15 has fixed wings......no swinging there.
The F-111 would be another good swingwing project.
Good Luck.
