Loosely read thru the thread and I woukd like to offer some words of " advice".... NEVER give up on your dream project no matter how long it may take to complete. Your skills will be improved, your knowkedge of how things work will improve, and maybe..HOPEFULLY you'll have that AH HA moment and BANG ya got a model that WOWS the world.
Modeling is a mararthon not always a sprint, I would love to build a 747SP " SOPHIA", I have decals, but the kit requires ALOT of surgery. My skils are close, my confidence nit so much but I still build...well try anyway.
My long winded point is you are on the right track, asking questions, looking for encouragement, gathering materials. I wish you the best of luck.
Perhaps trying a conversion of a cheaper, less detailed, or less expensive kit to give you a good foundation for the structural changes that will be required. Can't hurt, you will learn and probably drag a bunch of us along for the ride.
Go Star Blazers!!
