I think this is a great idea but I would recommend going back to the OLD SCHOOL & think about something more manageble, both in terms of vessel size & flying compliment.
Why not consider the first real carrier to make an appearance: USS Langley commissioned as CV-1 in 1922 & sunk in action in the Java Sea in 1942. At 520' x 65' she would be a manageble in 1/32 or 1/48 scale & not break the bank. The open deck would allow you a better chance of landing unscathed on that small surface without colliding with an island. Electric biplanes with their added lift & light weight would allow a short takeoff as well as a slow landing approach.
Of course, you can also consider the same with a contemporary from other side of the pond by building an early IJN carrier like Akagi or Kaga.
