i recently tried configuring pebbble with a similar dhcpd setup and found
this approach won't work.    i could have multiple subnets on a single
interface but dhcp would only provide leases in the first subnet.
if i added the alias interfaces to the /etc/default/dhcp file, then
the dhcp server wouldn't start.

my reason was different, i was building a repeater and had two pcmcia
wireless cards for radio links for the backbone network, and one physical
ethernet interface that fed two AP's connected to sector antennas for
clients and a third range of addresses for hosts on wired ethernet at
the site.   i was configuring for /26 subnets instead of the proposed
/30.
