Wow! Very impressive! I would not have expected such a converter to have been found for a long time (and certainly not this cheaply). One of the gliders can be moved to make this less obtrusive, and allow its use in many situations where one side the modified pattern protrudes beyond the lane the barber-pole is in on one side, but not the other. While there are few cases I can think of where this converter is advantageous, it IS useful for adding tripoles, because that takes around 20 gliders, while adding a quadpole takes only 7, and shorting it another 7, saving 6 gliders. (This does not help with bipoles, because adding a bipole is cheaper than shortening a quadpole twice.)
I have tried applying this to all my syntheses involving tripoles. This improves 5 oscillator syntheses. It also improves 5 pseudo-oscillator syntheses; the last one requires a slight alteration of this method, but it could not previously be done this way at all, so this dramatically reduces the cost from 41 to 20 gliders. I currently have 5 syntheses that cannot currently be improved because they protrude on both sides; 3 of these are pseudo-objects, formed from the 3 still-lifes that I originally found most challenging when first investingating pseudo-object syntheses. There are 133 other syntheses where this improves an alternate synthesis, but not the minimal one.
