Just an idea, untested:

1. Mark addresses to drop in RCPT TO: ACL:
warn
    ... <preconditions to "drop" this recipient> ...
    senders    = user1
    recipients = user2 : user4


    set acl_m_blackhole = $acl_m_blackhole $local_part@$domain=1


Basically you create list of addresses to blackhole in acl variable.

2. Create redirect router (early in routers list) to do the dirty work:

blackholes:
    debug_print = "R: blackholes for $local_part@$domain"
    driver = redirect
    data = :blackhole:
    # extract actual destination address from that list
    condition = \
        ${extract{$local_part@$domain}{$acl_m_blackhole}{$value}{0}}
