    It's not a big problem for f5 devices. Of course it's better to have a separate VLAN for each traffic: MGMT, HA, DMZ, External, etc. But if you can't, that's not a big deal, big-ip DSC cluster can work with those two VLAN also. You can use Internal VLAN for Config-Sync and for HA you can use either MGMT or the same Internal VLAN.

Just pay attention to port lockdown feature, as you need (if I'm correct 1026/UDP for failover).
