Hmm.. this is an interesting dilemma. My suggestion would be to
firmly grasp your L3 switch, tilt it sideways and forcefully shove it
into your rectum. Once inserted, the switch should be able to pass
traffic from both subnets without the need to configure a separate
gateway.

define a secondary adress on your L3 switch in the same vlan interface

from cisco sample ( I don't know hp l3 )
interface Vlan999
ip address 10.0.0.254 255.255.255.0 secondary
ip address 172.20.176.254 255.255.255.0

I think I just did something similar, and posted a question a few days
ago. "redhat FC8 routing problem"

Its out of the context of vlans but it would seem that you could
configure the host to use whatever gateway you wanted, as long as the
host has a route to the gateway.

(refer to other thread for diagram)
