Thanks for the responses. The reason I'm looking at doing this is that we

No you don't. It's advised, but not mandatory.
Nowadays having swap twice as RAM is not necessary. If your system wasn't
swapping much in the past you can safely stay with 4G in my opinion...
extending it to 16G would be waste of space :)
I won't bore you with the details but in fact our application *does* require
this much swap space, but

It's easy to *try* the swap files. Then measure the performance.
If the behaviour is really as specific to your custom application as you
indicate, then general advice may not apply either.
In fact, after discussing this with the team, we are going to do exactly that.
We'll allocate an extra

Are there any advantages to using mdconfig and creating a virtual disk for swap
space as opposed to having a designated swap partition? For example, I could do
something like this:
mdconfig -a -t swap -f /var/swap0 -s 4g
swapon -a /dev/md0
to add 4G to the system swap space backed by the file
