Smaller roasting pan? Sorry that's all I can think of

No, even a small turkey wont fit in this oven! I don't like the breast meat, so that's not an option either.

I don't know how big your kitchen is, but you could add a freestanding cooker/stove and oven. Electric oven you plug into the mains and gas top that you attach to the mains or get a bottle for, depending on where you are. Loads of brands available, but Smeg is very good and reliable. We did this, planning to replace the small oven and separate cook top, but ended up keeping them as it is great to have two cooking areas and the small oven is handy for cooking smaller dishes, heating plates, baking a cake while roasting dinner in the other oven, etc. I hope that helps.
