I think it's instructive to consider what things can change and what things can't as a bike is sized up or down. Obviously, the tubes can be made longer or shorter. Stems can be made with more or less "reach". But wheels only come in discrete sizes, and there generally are not fine variations in size for cranks, handlebars, brake levers, etc.
There are ...

Assuming, as the questioner did, that we are not considering cabling and such, Whether or not to put the stem facing forward or backwards depends on the handlebar shape and placement as well as where you hold the handlebar. I think the physics of bicycle stability is pretty complicated, in any case.
There may be analogies between holding an automobile ...

The idea here is that a frame is typically originally designed in a 56cm frame, or the equivalent median size for the "average size" rider.
When the frame design is tested and finalized, most manufacturers minimize the changes they make when creating the molds for additional sizes.
This can result in small sizes having a harsher ride than the median, and ...

I have recently assembled a bike from used parts, and the last bit of adjustment was precisely the stem length.
Two criteria were key to decide the right length, and they didn't have anything to do with what I call "The Numerology of Bike Fit". Instead, I prefer functional criteria, that is:
How is the bike HANDLING? I thought I would need a stem of a ...

Bicycle size is determined first by frame size, which is top tube length, seat tube length, and some more minor geometries like head tube and seat tube angle. The primary determing factor for comfort on the bike is your reach measurement.
Although it is affected by various factors, like skeletal flexibility and the type of riding you do, ideal reach is ...

The top tube length, seat position, stem length, head angle, and bar design together determine "reach", which is the primary criterion here. Stem length also has an effect on stability.
Top tube length and seat tube length generally are tied together (in a non-custom frame), so a shorter top tube implies a shorter seat tube (ie, a "smaller" frame).
You ...

It seems to me that such an extreme position indicates a fit problem with the bike. Maybe that's what you should attack first.
