Ah sorry i didn't read all the way down to your question.
No you cannot.
The reason for that is that backends are exhausted for zone content in
the order in which they are specified in the launch statement and the
for loop breaks after the first backend answers something else than 'i
don't know', so the first to answer 'wins' one could say.
This means that your 'sec' backend will always answer first for the
content of the database.
However you don't need to serve the data via a dedicated 'sec' and
'non sec' backend as even if dnssec is enabled for a backend PowerDNS
will still serve that domain without dnssec perfectly normal.
Please compare the output of
dig soa zaphods.net @mandelbrot.zaphods.net +norec
dig soa zaphods.net @mandelbrot.zaphods.net +norec +dnssec
Enabling DNSSEC for a domain does not mean that a name server will
cease serving regular DNS content and protocol, it just means that it
will respond differently when 'DNSSEC OK' (DO) bit is set for a query.
Running `pdnssec rectify-zone wibble.com` will just add the 'mail' to
the ordername column of your records table btw. With DNSSEC in
non-narrow mode you need to run this whenever you change a record. I
suspect running it might already solve your problem.
