This one looks like the best

[Jormungant]

Indeed, that the best, or at least the bit is teasing you in believing that might be possible to complete, but really everything seem to produce excess block and gliders cannot pass through in the natural glider direction as soon as there is any still life in the way. Some interesting units can be made, but nothing seems to be reusable so to enable to make helix or xwsses. Found a way to make clean boat trails, which hopefully allow oblique glider through, but how to get those carefully placed blocks is not that clear, but one can somehow lay down blocks with some limited flexibility:

There is many creative ways to get rid of block trails, and provided that a "natural" glider in a specific lane, it effectively can pass through a block trail, but this moves the block trail in the process, making this a bit misleading:

addendum:
Among the ways blocks can be moved for "free" I just noticed that a pair of interaction actually allows the block to be shifted by the exact same amount in the opposite direction, as if there was not block trail (assuming the glider lane happen to match though)
