I am no subneting pro but:
Currently you have half DHCP and half statics...
How will it be with the /20? Still half/half?
$ ipcalc -nb 10.1.16.0/20
Address: 10.1.16.0
Netmask: 255.255.240.0 = 20
Wildcard: 0.0.15.255
=>
Network: 10.1.16.0/20
HostMin: 10.1.16.1
HostMax: 10.1.31.254
Broadcast: 10.1.31.255
Hosts/Net: 4094
A /20 half/half would give:
10.1.16.1-10.1.23.254
10.1.24.1-10.1.31.254

They would talk to 10.1.16.1-10.1.19.254 ones, but would go for the gateway for 10.1.20.1-10.1.31.254
