It's at least theoretically possible to cornershoot a tub if there's cells blocking the way, although this particular method seems like it might end up being expensive:

Code: Select all

x = 31, y = 11, rule = B3/S23

12b3o$4bo4bo14bo!

The predecessors start to look less contrived if you're able to non-destructively interact with the butterfly:

Code: Select all

x = 12, y = 12, rule = B3/S23
5b2o$3bo$3b2obo$5bobo$8bo$3b2o4bobo$3bo4bo2bo$2obo2bo2bo$bo2b3o2b2o$bo
$2b3o$4bo!

I didn't look too hard at asymmetric predecessors, and definitely haven't fully explored every idea, so it's likely there's something smaller.

EDIT: There might be an idea using a symmetrical methuselah such as this one:

Code: Select all

x = 11, y = 11, rule = B3/S23

xs19_4a5la4z69611 -20g to 16g (also from soup):

14G using octo3obj and the suggested method:

Code: Select all

66bobo$66bo3$34b2o$33bobo$35bo$60b3o$60bo$61bo25$90b2o$90bobo$90bo!

octo3g actually returned no results on generation 0 of the object you posted, but did return 19 results on generation 3, one of which fortunately worked. This is due to harmless sparks forming in the back, so it's usually very helpful to step an object ahead a few generations past its collision point just to make sure the sparks don't obscure results.
