The commemorative three color scheme on the Tomcat in that last image is one that I do not recall seeing before. What squadron is that from?
Your modifications for the landing gear attachments is a great idea. I hope it works and you have many flights around the hobby room. 
Thank you

Can't wait to be cleared for takeoff
The Squadron is VF-211 Checkmates.

I am not sure what to do about seats for the WWII backdated F-14
Should they be just classic WWII -era pilot seats or primitive, first generation-like ejection seats? 
I did some little checks in lego:

The goal is to have Santa bring me a 3d Printer, so Ejection seats may be more plentiful and in any type that I want soon.
I actually want to steer away from the F-14A GRU-7 ejection seats. Their cushions make me think of japanese aviators vests, so any spares are going to the Japanese models.

Some other random thoughts. I really try not to get bogged down in a back story. but one of the ideas I had with aircraft being designed around requirements is if this WWII F-14 was never intended to be super sonic, and how that would effect the design and weight etc. Another Idea I had was the Swing Wings that are meant for super sonic flight, could be just another folding method that carrier aircraft often incorporate to save room. So the wings would be "out" and locked all the time when flying, and only Swept for storage purposes.
I'm hoping in my next post I can kind of Quantify and show the various plans i have to mangle more Tomcats, but make it look nice and not just a list of future razor saw appointments.
