There appears to be no way-- no way whatsoever-- to move Pixelmon Spanwers once they've been placed.
Commands can't do it because, unlike every other block, if you break a spawner, it doesn't drop itself.
Carry-On can't do it, even if pick-up distances are maxed out (probably because you can only carry-on blocks you can reach, and as soon as you reach the block, it tells you 'only servers or OPs can interact with this block').
Not Enough Wands can't do it, it complains the 'block is too hard to take' even when settings are maxed out. (also Not Enough Wands can't change in immersive Engineering's charging station, but tries to do so, and that buggy interaction is sucky.)
One possible solution is to work out how the shulker box drops itself with its nbt data intact, and then to try and update the loot table for the pixelmon spawner so that it drops itself. This would allow the 'break by command' strategy to work.
