Here's one that is free and easy to do.
At 5' 4", my Mrs also has small hands. She rotated her bars forward and slightly further down, so she could comfortably reach everything.
What we found is that the hands sit further round over the top of the grips - Not massively, but enough that the controls are easier for her to reach.
Try that and see how you get on.
I can take a couple of illustrative pictures, if you like?
Also, her brake is very firm and the clutch is adjusted to bite when the lever is less than an inch away from the grip. Every time I ride her bike I stall it at least once, ha ha!!!
