Not with the highest efficiency.
In current setup each seed has
2 molds, 1 other foliage (3 occupied) and 21 empty air blocks.
Changing anything on this setup takes efficiency down. You still get some results, with one additional block changed it still good, but i your pattern the seed in the middle has more than 10 additional blocks occupied.
Roughly like this… red marked what is more than optimum and turns the efficiency down
