If it wasn't for the last part of your statement I would have suggested using your feet. I think though that you'll be going with one of the teleconverter options (1.4x 1.5x 1.7x 2x 3x). Each has it's strengths and weaknesses, the weakest of each is that good ones for Pentax are very difficult (and expensive) to find.
There are also the front teleconverters that are basically heavy magnifying glasses but I don't know much about them, nor, how the plastic thread on the FA will handle them.
Instead of going through all that though, you might just be better off with a zoom or telephoto lens. Remember that with a TC, your f1.4 does not Stay at f1.4. A 2x for instance, your lens will become an f2.8 lens. I don't think it has the nice rendering of the FA50 but you can get a Pentax 135 f2.5 (or 2.8?) Takumar (bayonet) for less than the cost of most decent teleconverters. In fact you can probably buy 2 or 3 of them.
Good luck..
