Hello!
As you probably noticed you are essentially scratchbuilding that Hampden - I mean you're starting from almost zero. That needs a different approach than a "normal" plastic kit. In case of a "normal" kit you focus on what's in the box. In case of that Hampden you need to focus on what is NOT in your box - things like engines, landing gear, guns and so on would probably have to be "organized" from somewhere. And you need to know your subject to know how it should look like - for example at what angle the wings and stabilizers should be mounted. It's a lot of work and it may be that all the work isn't worth it for you - you have to decide that as your first thing.
Then again the only non-vacu kit of the Hampden in 1:48 is a Fonderie Miniatures short run and a 1:48 Hampden could turn out looking good. Vacu kits are believed to lend themselves better to things like opening up doors and showing the interior if that's your thing.
One thing for sure - if you decide to build it you will need a lot of creativity and you will need to make a lot of parts from zero. And after that your model buildning will never be the same again.
So - I hope you will post some photos of that and I wish you luck whatever you decide to do
