Not really, as long as you make 1ms = 1ms etc. Initialisation timing
for the LCD is important, and it's often the cause of a blank screen.

And of course make the changes that you need for a 16F

The macro I use for 1 usec (seeing as it's generally a 452 and space
isn't tight so a few of these won't be a problem)

usec     macro                ;1us delay
         movff   temp,temp
         movff   temp,temp
         movff   temp,temp
         movff   temp,temp
         movff   temp,temp
         endm

is based on a 200ns instruction cycle. Yours is 1us per IC, so you
can use a single NOP. It's generally OK with an LCD to have as
little as 1us between BCF/BSF etc on a port driving RS/RW/EN,
but more won't hurt and, although I've never had a problem, would
be safer.

The 44780 is fast-ish, for example

Enable cycle time, 1000ns min
Enable pulse width, 450ns min
