Vin, going with a aircraft grade stripper might (probably) go into the plane. You might experiment with it. Sanding IMO would be the way to go. The heavy wet/dry used with water then go up to fine grades. Maybe have a sanding party with some friends and weight each piece before and after, ie wing panels. Offer a prize to the best sander!haha!
I have not done this to a plane but have removed auto paint at work. I am a set painter. Experiment is an unseen area. Painting over would be the easy way out and the weight savings from removal might not be a big deal to you. Is there a texture to your current design or is it smooth?
I like you paint scheme now, but it is a bit busy.
