Regarding the memory-to-memory stack-machine, such a configuration would obviously also solve the issue of instruction size, while improving preservation of state, and a bit-serial architecture would improve the ease of making variable length operations. There are some obvious flaws though, moves become far less elegant than in a pure memory-to-memory architecture, and there would need to be some mechanism for linking the element of the stack wasting some of the memory won by being bit-addressable.
