No, it won't work because the /proc/net/arp is ARP cache actually :( I've just
checked it just after I've pressed the send key, from the man page:

"
/proc/net/arp

This holds an ASCII readable dump of the kernel ARP table used
for address resolutions.  It will show both dynamically learned and pre-pro‐
grammed ARP entries.
"

So it seems, that your solution is the only possible I'm aware of.
