@Gashnaw: I believe this hex edit should do it:
org $00F129 BEQ $00
Of course, you can also create a block which does this but a patch is much easier, given that you need to recreate the coin.
That being said, tt seems like the blocks from the switch pack do the job as fine too unless the path has to stay open.
By the way, if you need to revert the hex edit, just apply this edit instead:
org $00F129 BEQ $29
