mod_security + apache + geoip block != 404

Question

I have plenty of bots accessing the site trying to find holes and stuff like that, so my idea was to block all non .se visitors (i dont mind google getting blocked either), that part works like a charm, but the response is 200, but i would like to give them 404 instead, any ideas?

I have this in my apache.conf

<IfModule mod_security2.c>

    SecRuleEngine On

    SecAuditEngine RelevantOnly
    SecAuditLog /var/log/apache2/audit_log

    SecDebugLog /var/log/apache2/modsec_debug_log
    SecDebugLogLevel 0

    SecRequestBodyAccess On
    SecResponseBodyAccess Off

    SecDefaultAction "phase:2,deny,log,status:500"

    SecGeoLookupDb /usr/local/share/GeoIP/GeoIP.dat
    SecRule REMOTE_ADDR "@geoLookup" "chain,drop,msg:'Non-SE IP address'"
    SecRule GEO:COUNTRY_CODE "!@streq SE" "t:none"

</IfModule>
