Thanks for asking. I did end up having to Dremel just a little bit off the corner of the wood to get them to twist correctly. I'd test fit them flat, but the diagonal was just a little longer than the straight line, of course.
Final electrical test has a draw of between .66 and .68A depending on the unit. At a voltage of 13.8 (at blinker socket with engine running), that comes out to 9.3 watts. Factory blinkers are 23 watts, so each side will now draw 18W vs 46W originally, and no filament to break.
Installed on the bike.
Test, cover off.
Cover back on.
Directly from the side.
LED left, bulb right. Not quite as bright, but perfectly adequate.
