Switching the order of exercises

For instance (just a completely random example!):

Workout A:

FL

MN

SL

SLS

Workout B:

RC

HBP

SpL

Is it acceptable to do so?

Yes, switching the order around is acceptable.

This makes things easier.

I don't switch the days the program assigned exercise to me, but I do switch the order within the day.   I start out with the one I am at lowest progression on and work my way towards the highest progression.  This is an effort to work on the biggest weakness and try to keep things in balance.
