Before you decide to do this, I suggest you buy one, get your software
running, and see if you like it.  We have lots of users here using AT&T
6300's as terminals.  (The 6300 has an 8MHz 8086 which will do at least
as well as what you describe.)  The terminal emulation programs don't come
anywhere near 19200 bps; typical throughput is more likd 2400 bps or so.
(I can't remember the exact figures, it might have been as high as 4000
bps.  But it was nowhere near 19200.  And it does vary from program to
program.)

The 6300 display board does snow, just like the official IBM color card,
so if you can arrange to get a non-snowing card, and have your program
know about it, you might speed things up a bit.

The other problem is that the typical PC comes with a horribly braindamaged
keyboard.  Most terminals come with reasonable keyboards, except the
VT200 series and clones.  You can get a Keytronics keyboard, but you
may not like the feel, and they will add $200 to your cost for the 5151.
(If you can find a 5150 and like it, it may cost considerably less.)
